to. >> i bet you the democrats are saying is there a statue of limitations. >> the democrats say one of them said, we bought a knife to a gunfight. >> thank you so much. can't wait to see it. you can watch the full story tomorrow night, 9:00 p.m. right here on cnn. do not my it. i'm dana bash in washington. gps starts right now. this is gps, the global public square. welcome to all you have in the united states and around the world. we have an important show for you today starting with syria. for years president obama has been insistent, emphatic. >> i will not put american boots on the ground in sir. >> now up to 50 special force troop will go. why the change in policy? i'll explore that.

the u.s. defense secretary says that president obama is considering direct action on the ground there. we will take you inside the administration's thinking on iraq with deputy secretary of state. then, it's one year and one week until the election. all eyes already on the polls. what do they lareally tell us a will today's front-runners be tomorrow's nominees. also from one child to to. china changes decades of policy. it's hoping to grow its economy by growing its family. will it work? one of the world's most famous scientists on dr. ben carson's rejection of the theory of evolution. >> this is not something you believe in or not. it's fact.

it's fact. it's just as much a fact as the earth goes around the sun. >> here's my take. i had an interesting visitor drop by my office last week, and he said something that stuck with me. the most important contest in the world right now, he said, is between isis and us. he is rasheed, the intellectual leader. despite winning the country's first free elections compromised with its political foes and helped make tunisia the arab springs only success. as he sees it, the real struggle is not between islam and the west but between the isis model and the tunisian model. the only way to beat isis is to offer a better product to the millions of young muslims in the

world. that better product needs to be a political system and respects human rights but also allows islam and its values some space within the political system. we are building the alternative model in tunisia, he told me proudly. his success story is quite fragile. not quite the fairy tale version that's recounted. they were reluctant to compromise. they left power only because they thought the country would explode if they didn't. key elements of the old guard have returned in force and the place remains fragile with the economy under severe pressure. most transitions to democracy are marked by bitter struggles. democracy did not come to south korea or taiwan or chile. the dictators resisted fiercely. it's only in retro spect that

one can look back and peace calmly of peaceful democratic transitions. in a conversation with the country's head of government, i asked him to explain the country's success. he pointed to three things. first he said tunisia has existed as a political entity for 3,000 years from the times of ancient carthage. it does not have the sectarian and tribal differences. third he explained that on the first post-independence leader tunisia built strong political and administrative institutions. in addition to all these structural advantages it's benefits from wide leadership. the old order, the elites were still very powerful so the

country wouldn't be run by excludesing them. he noted that you cannot go for total victory. in mature democracies, perhaps the party that up with of the polls would have its way but gives the youth and fragility it's leaders decided to go for consensus and compromise. we lost power. we won tunisia. he remained surprisingly optimistic about the arab spring. people will not go back to the old ways of tyranny. like the french revolution the arab spring has produced turmoil and violence and reaction but it will transform all these de dictatorships in the muslim world. that's a note of optimism in a bleak landscape. for more go to cnn.com/fareed and read my washington post column this week. let's get started.

what to make of the white house's apparent bout face. the decision to spend 50 special operations forces into syria after saying for years it would not put boots on the ground. joining me now is richard at the state department. he joins me from the council on foreign relations where he's the president. is this a big shift or just an enhancement of an existing mission? >> it's probably closer to that. it's a significant shift. it's meant to correct the basic deficiency in u.s. policy where we haven't had a ground partner for years and we've learned we can't do it from the air or create aground partner. . >> i understand the tactical

issue here which is kind of just allows the u.s. to operate militarily more effectively but it's partnering with the kurd even though they present it's a multi-ethnic force. the kurds don't want to go into rocca, defeat isis and take control of syria. they just want their enclave. it's almost like a humanitarian intervention rather than a political military one to take control of syria. >> exactly right. this is not an all syria strategy. it's not wildly ambitious. i don't mean to diminish what it is. it's not the beginning of restoring syria as a country. this is to stabilize syria. what you'll end up with if this succeeds, probably for years is a syria of four, five, six enclaves.

that's the definition of success here. >> what i'm worried about is there is a tendency in these situations to do tactical things that enhance your position that are more effective. you don't think a lot about the strategy. what i'm trying to figure out is what the is strategy if this succeeds? you take over towns like rocca and you have a bunch of kurds who are in charge of rocca or kurds assisted by americans. that's not going to go over well with the 85% sunni population.

>> i think this stabilizes the situation, keeps a bad situation from continuing to get worse. it then buys you time by freezing or slowing the situation on the ground. i think that's part of the goal which is over time the united states with russia, i realize it's something of a long shot, can talk about a political transition into damascus. what we need is partner in damascus we can work with. we would work with some transitional successor government. this could buy you time until you get to that point. >> what do you think of the idea of iran being invited to join the talks? they are crucially involved. helping the regime. it's helping the regime. they are a big player on the ground. would that translate into them

being helpful at the negotiating table in geneva. >> the iranian vs have to worry about the middle east. i think they understand that at some point in this process assad has to go. they wouldn't do it as favor to us. they'd do it as a favor to themselves. i think the russians understand the same thing. we have to be flexible. i can't sit here and tell you we're going to be able to partner with the iranians here. it's worth trying. by working with the kurds and some arabs we can perhaps slow the momentum of isis which will help get more kurds and arabs to work with us. it helps make the situation on the ground from getting worse. at least it creates a backdrop where diplomacy can succeed. right knew now we have no

backdrop. we have an imbalance of power that works against us. this could lead to balance of power that more works in our favor. >> do you think that between the 3,5 3,500 troops in iraq, now the 50 in syria, be united states is engaged in way they will be more in control of situation? what i worry about is at the end of the day this is a very deep sectarian divide. you described it as the middle east 30-year war. can we shape the outcome with these incremental pointed intervention interventions? >> it's the right thing to say. i think that's only true if your goal is to win war in the traditional sense. i don't think it's our goal to

restore iraq. i don't think it's our goal to restore functioning national syria. i would say our goal is to keep as many innocent people alife and keep the terrorists from roll up territory. i think our goal is what we want to prevent the even that relatively modest goal will turn out to be sufficient. i think the announcement made over this week is consistent with trying to keep the middle east from going over the cliff rather than trying to remake the middle east in our image. >> stop it from blowing up anymore. very, very interesting conversation. thank you so much. >> thank you. now from syria to iraq. the united states is talking about putting a handful of troops in syria, but already has thousands in iraq. how should we think about the

united states's past and future involvement in iraq? you'll hear from the deputy secretary of state, next.

without drastic measures. stunningly youthful award winning skin. never settle for anything less. the regenerist collection, from the world's #1. olay, your best beautiful. here is the number 50. that's the top limit of how many special operations forces the white house says it intends to send to syria as you heard in the last segment. here is a much bigger number. 3,500. that's how many troops the united states already has in iraq fighting isis. ten days ago, one of them was killed. master sergeant joshua wheeler. he was the first american so soldier to die under enemy fire in iraq in four years there. >> we will deliver isil is lasting defeat.

>> is the united states back in business in iraq? ash carter said this week before the senate arms services committee that the u.s. was considering direct action on the ground. you're about to see an interview i did for my documentary which i did this past monday. he's deputy national security advisory to obama and national security advisor to biden. >> at the end of the day the iraqis wants us out.

that's what happened. the body politics was clear on that. the really group that really wanted us to stay was the kurds. they didn't believe it, every step of the way we designed a glide path that would gradually pull us out of iraq. at every step along the way the iraqis didn't believe we would follow through. they didn't believe we would get out of the cities, we did. they didn't believe we would end our combat mission. we had to prove to them that we meant it. in my judgment, at least, we actually had to leave in order to reengage later and get back in. >> to what extent do you think you do have a coherent, functioning partner in iraq today? >> we have an increasingly functioning partner in iraq. it's a work in progress. it was important to have a partner on the ground because it

was our firm belief in the experience of the last decade that the most effective and sustainable way to deal with this problem was to have people who are willing to fight for their own country, do the work on the ground with our very strong support, with our air support, intelligence, weapons, advice. people taking back their own country. in the past year, as a result of these efforts and as result of much greater coherence among the iraqis and the coalition, the territory that isis controls is down 35% from where it was when the coalition was first formed. thousands of isil members have been killed. much of their material has been destroyed. in many parts of iraq, they are on their heels, not on their toes. they're still capable of taking the initiative. they still have a base and

sanctuary in syria. the one part of iraq where things have been much more difficult is ambar province because of this conflict. what's changed is this was a problem. to bring them in. to populate the beginnings of the national guard and bring more of them into the iraqi army itself. to get more control that have shia militia in them to to stabilize areas that were newly liberated. we're seeing that start, let me emphasize start.

people will make their judgments about the war whether it was wise to get into it, the way we got into it, the way we prosecuted it. by the time the obama administration came into office, that was an inheritance that we had to deal with. we were determined to make the best possible future we could for iraq and live up to that responsibility. that's what we tried to do. i think there were moments in the last years when you could see and we can still see way for iraq. it depends on the iraqs

themselves. they have to decide the future of the country. they have to decide the future depends on them and not a cross purposes. that says the united states can affect these regions or the future. >> the question is not whether we can affect them. i think we can. the question is whether what we do can truly be dispositive in shaping their future. i think it's our police chief th -- belief that it's up to the people. we can help. we can push. we can prod. we can support, but it's not up to us. it comes back to this basic proposition that most of these problems are not about us. by definition, there's not some simple solution that is within

the power of the united states. it has to be them. the question is what can we do, if anything, to maximize the potential for a positive outcome and minimize the potential for a negative one. >> that interview was part of our latest special "long road to hell, america in iraq" if you missed it stay tuned to my facebook and twitter accounts on when the show will reair. next, why in the world did china just reverse nearly four decades of policy deictating ho many children its citizens can bear. i'll tell you why western leaders should pay attention.

now for our what in the world sessigment. china made a decision that will change the course of that country and the world. after four days of intense meetings, beijing announced it would end its one child policy which forbade many chinese

couples from having multiple children. all couples in china will be allowed to have two children. this was an admission that china's greatest obstacle to continue growth in the long run was its demographics. it would have too few young workers and too many old retirees. china would grow old before it would grow rich. this new policy aims to change the fate. i remember when the policy was adopted in the late 1970s. people were envious of china's ability to force china's family planning. india was chaotic. the incentive for smaller families didn't seem to do much to keep family sizes down. poor countries have little money and many mouths to feed.

the policies behind them turned out to be wrong. in 1968 a stanford biology wrote a book titled the population bomb. he warned we did not have the resources for the number of people on the planet. today the earth's population is twice what it was in 1968. we have innovative ways not just to survive but prosper. however, the idea persists that our big problem is too many people. as we recently noted in the wall street journal the united nations says we will add over two billion people to the world's population in the next 35 years implying an unmanageable strain on our resources. the problem might be the reverse. as countries develop their birthrates plunge.

work population growth which is averaged nearly 2% is about 1%. couples are not replacing themselves. even in a poor country like india, the fertility rate has plummeted. couples use to have six children and now the average is less than three. the real problem the rich world faces acutely, particularly europe is a population implosion. only the countries that adapt early to the population implosion will thrive in the baby bust era. he predicts that countries will only be able to thrive economically if they become friendly to immigrants or convince their people to have more babies, which is much harder. china's technocrates have

studied the data and trying to adjust to the new realities out there. will western politicians follow suit? next, the 2016 presidential horse race. who's up, who's down? more importantly, what all of those numbers actually mean and do they mean anything at all? you wouldn't order szechuan without checking the spice level. it really opens the passages. waiter. water. so why would you invest without checking brokercheck? check your broker with brokercheck. ♪jake reese, "day to feel alive"♪ ♪jake reese, "day to feel alive"♪

. carson is now ahead. hillary has a solid lead but bernie is rising in iowa. when ever i see headlines about the race and hear news reports, i swatch my head and wonder what to think. what should i pay attention to? what should i ignore? how will anyone know when there's so many republican candidates in the field. i brought in two actual experts to help me understand. joining me now the queen of polling in iowa. she runs the polling firm selsa and company based in des moines,

iowa. that first question, with the huge field like this, i stiels think to myself how would one figure out, for example. there is some kind of anti-trump vote or non-trump vote. is there way to figure out when it goes down to four? >> we have some signals about how that will look. i agree with you. when we started polling, looking at our preliminary data how will we set with the tiers are, you have a top tier but the middle tier is gigantic and people that don't even score. we were saying we have to look at more than just the horse race question. with a little intex we put together we created way to see marco rubio had upside potential way early when we first started. >> why?

what were you attesting to that? >> he had a high number for second choice and very high number of people who say he's not my first or second choice but i could see myself ever voting for him. you only get one vote. >> do you think at the end of the day the republicans will end up with a conventional candidate? >> i think so. the polls do not reflect where the results will be in the next few months. a lot is going to change. >> they all went onto lose at this point.

what we're seeing now is republican voters haven't begun to think much ant this race. they are just now beginning the tune in. they will change their minds a lot. what we're seeing is a reflection of the media and the debates. >> can the debates, you've been doing this for a long time, can performance in a debate really boost people's viability to the point that it starts registering? >> the one i'm remembering is before i was doing the polling and it was george mcgovern in the 1984 debate who was the only statesman presenting himself that way and saying if you don't think i can win, then you vote whoever it is you want. if you want to send a message about what you want out of your democratic candidate, vote for me. he surged up to third place. he'd been polling very low. debates do matter. >> a lot of people look at iowa and say this rural agriculture

state with huge numbers of evangelicals, why do they get to go first? >> you can make the argument that iowa is the worst place to start the contest except for every place else. you're going to start it somewhere. the benefit that iowa has is you can conquer the state. you can't conquer california in a meaningful way, in a personal way. you can't conquer texas. iowa you can go to sioux county and meet the people. you've got to organize people to show up. it really is a test of a campaign's ability to get things done in way isn't as true in other states. >> i think people look at who is at the top of the polls and they are impressed with donald trump up there. there's a lot of candidates with

a lot less that's gone to win. the reality is it in not take a lot of votes to win iowa. it's a low turn out race with a lot of people in field. you only need a small smegment to get behind you. i don't know that the way people are reading the polls right now focusing on a flashing number at the top is really going to say very much about how it will end up. >> that's true on the republican side. >> the democratic side may be as clear as it looks. hillary clinton may well be on a easy victory nationally. >> we don't know. i never make predictions because they always include a wish. >> flpleasure to have you on. one of the world's greatest scientists on why the republican front-runners, especially those who should know better, don't seem to understand science. the promise of the cloud is that every organization

eventually applying his theory of evolution applying it to all animals. the opposing theory is creationism which states god created men and women in his own image as the bible states. according to the pugh research center 98% of the professional scientists believe that humans and other living things have evolved over time. when the american public was polled just 65% said they believe that. of the gop candidates, almost none of them seem to believe it. richard dawkins is a long time

professor who has written. he has a brief resource out. >> if i look at the united states, currently the republican presidential candidates as far as i know, every single one of the declared candidates with the exception of trump about whom one doesn't know which way he would add, when asked about evolution say they don't believe it and jeb bush was asked. he said i sort of believe it but i don't think it should be taught in school. >> this is not something you believe in or not. this is a fact. it is a fact. it's just as much as fact as the earth goes around the sun. you can't not believe it unless you're ignorant. i believe they are ignorant. they think they have got to say

that in order to appeal to their constituency. if that's true, it's deeply depressing. >> you talk about some of this. how would you explain to somebody who says i don't believe in evolution. what do you use is the most powerful evidence. >> i think the most powerful evidence is not fossils. fossils are the main evidence for the actual history of life. the most powerful evidence that evolution has happened is probably molecular genetics. in darwin's time the comparative data, you look to human hand and compare it with a bat's wing, a whale's flipper, alion's paw. you see the same bones. you can identify them bone for bone. that was in darwin's time. now question do that same kind of thing but with molecules and coded letters of dna. do you can look at long reams of

code. the letter by letter exactly as you might compare two versions of the book of jeremiah. it's letter for letter comparison. you can count the number of differences this millions between humans and chimps and monkeys. you can take any two animals you like and look at their molecules and count the number of letters that are different. that is just so overwhelmingly strong evidence. darwin would have loved it. >> what do you say to ben carson who teaches medicine at yale. he says he's a creationist. he thinks that god created the world and you're going to tell me the complexity of the human brain and he's a brain surgeon came out of a soup full of chemicals and such. >> i'm going to tell him not but

not subtly. it took a long time. that's what these people don't understand. they think it all happened suddenly. if you think that, of course you don't believe it. it couldn't happen suddenly but if it happens gradually. each stage is only a tiny bit different from the one before then you can start understanding it. you told me all the republican candidates except one don't believe in evolution, that's a disgrace. for a distinguished doctor, as he is, to say that is even worse. hea evolution is the bedrock of biology. for a distinguished doctor to not understand, he clearly doesn't understand the fundamental theory of his own subject. that's a terrible indictment. >> it's a theory like all of

science is a theory in the sense it does rest on evidence. >> we've got to stop calling it a theory because it's misunderstood. evolution is fact. >> it's another way of putting it's a theory that's been confirmed by throw saousands of. >> mutually confirming pieces of data. >> carson, i'm dwelling on him because he's a republican candidate. he's what a lot of people think. this represents the height of arrogance of humans to believe they would understand god's mystery. >> i wouldn't call him arrogant. he's a nice man. i met him. it is a form of arrogance to say we know what god does. in this case the evidence is overwhelming.

there's plenty of idea where is scientist isn't overwhelming. there's no doubt. it is fact. >> pleasure to have you on. >> great pleasure as always. thank you very much. next, if you think american politics is a joke, well let me introduce do you a new world leader who is an actual comedian. where in the world is it? find out when we come wac. is never easy. doing your own thing, making your own way

nnch . in the last few months we witnessed dr. ben carson and donald trump overshadow

established politicians. what country has elected a professional comedian who never held political office as its president? stay tune andwell tell you the correct answer. one of the great and real what ifs of history is this. what if israel's prime minister has not been assassinated in 1995. a decorated war hero he seemed determined to make peace with the palestinians and forge a two-state solution. in this fast paced well written book he takes us through the fascinating crucial moment in middle eastern history. now for the last look. on tuesday a guided missile destroyer called the uss lasin

passed within 12 nautical miles of reclanimed islands. creating islands out of next to nothing is what has led to all this trouble in first place. the defense department says that over the past two years china has reclaimed almost 3,000 acres of artificial islands in the south china sea. an area sought after for its strategic maritime position. so rich with resources that some call it the second persian gulf. it was totally transformed this year. this one fiery cross reef was built up in a year. according to the defense department in just 20 months china reclaimed 17 times more land than vietnam, malaysia and taiwan have claimed over the past 40 years combined.

china continues to worry neighbors with the construction of facilities on the islands including a 3,000 meter. the u.s. warned this week its patrols are expected to become more frequent. the chinese foreign ministry says if the u.s. keeps stirring it up, it will be necessary for china to speed up its construction activities as the new york times pointed out. this is one case in which china ease speed and efficiency to get stuff built will cause more problems than it solves. the correct answer is c. television media was elected in land slide victory. he had just 1% of the polls in april surged with a clear slogan, not corrupt, not a thief.
