set of promises for all the government can do to deliver and really solve all of the problems of humankind and the reagan alternative of government not being a solution to the problem but is the problem itself. but that is a pretty impossible standard told lyndon johnson to and the moment to beat this guy, ronald reagan, all the possible threat is in a lot of ways going to be the one that has the largest effect on his legacy. so i would say that looking at history, i hope that in my current political reporting how will be a little more charitable toward politicians in the expectation of what they should understand about the country. remind me of the second half of your question. >> how has politics itself change in that 50 years between the 64 election and that 2004 election? >> it has changed in a lot of ways. you know, my book deals with the thousand days after the kennedy assassination, which if you want to look at a moment in time where politicians actually got stuff done as opposed to what i think we all feel like today with a can get anything done, is a fantastic moment. with the pre

and then, i mean, why should journalists be protected and the rest of humankind nod be protected. there are legal problems, but the key is holding governments and non-start party arrangements accountable. in arab worlds we see al jazeera journalists in gaol on trumped up charges. no one is holding the government accountable. people are beaten up in the street. cameras broken. unless governments start questioning people, bring them to court, taking them to justice, and verdicts, heavy fines and imprisonments are holding the beam accountable. this will continue. >> let me pick up on the point. the three al jazeera staff were serving their prison sentences in cairo, they are the public faces of the threats facing all journalists. on the other side, where do governments draw the line between protecting security and targetting journalists. >> egypt, like in other places, the run party coming in defending the area are either complicit or they are part of the problem. egypt or the number of gos are threatening to be closed down. there's a lot of problems with the journalist union because

here is a vision of one planet and one family of humankind. but the view from earth reminds us of a common human dilemma, the rise and fall of our many ways of life. here, among the ruins of ancient civilizations, archaeologists are retracing the steps in a long and shared human odyssey. across two worlds, the old and the new, they are discovering the independent spark of the human genius, the many times and places that we have created grand civilizations. ancient egypt. as early as the 18th century, scholars came here to marvel at and study the great relics of the ancient sun kings. laboring among the pyramids and temples of this old-world civilization, early archaeologists speculated that complex civilizations were created in the near east to spread far and wide. they thought the greek city states, the roman empire, and all the civilizations that followed were the inheritors of a single act of creation. but discoveries in the new world would provide a stunning challenge to this myopic vision of human history. in 1839, in the jungles of mesoa

. >>> also, 300 million miles from here, some news today about humankind having pulled off the amazing achievement of landing a spacecraft on a speeding comet. as we reported on last night's show, one of the concerns about that mission is that there's not very much gravity on the comet. it's only about 1/10000th of the comet would be at risk of floating away, basically not being able to stick to the comet once it landed there. well, we talked about that last night on the show. the problem of the comet lander floating away, in fact, has happened now twice in the past 24 hours. the little landing craft can't stick. it just floated away for a while into space before eventually coming back down on the come et today. the problem now is that it has come back down on a place that is shady, a place that is shielding its solar panels from the sun. so at risk of running out of energy and dying on the comet unless it can get to a sunny spot. the question now is whether they're going to be able to shove it off into space again on purpose and hope that the next time it comes down on the comet, it c

is passing all these programs he communicates to the country as though these problems that affect humankind throughout its history are within reach of solving. he wins his landslide election in 1964 and he goes before the country and he says, these are the most hopeful times since christ was born in bethlehem. tonight that reagan gives the speech, the time for choosing speech in october of 1964, johnson is on the other side of the country and he says it's a time of peace on earth and goodwill among men, the place is here and the time is now. that's a pretty remarkable expectation for government. and it is inevitably going to fail to meet the. and when it does, not only fails to meet that expectation, but then create a great climate of anxiety with conflict in vietnam, the apparent disintegration of the cities. that undermines people's faith in government altogether and i think that is in a lot of ways what gives the legitimacy to the reagan counter argument which is government essential is not the solution to all of our problems. in many ways government is the problem. and i think over time

we're going to get out of this comet from these experiments that will actually be significant for humankindis the first time a lander has successfully soft landed on a comet and so just besides the technical feat of doing that, the science we're going to learn, it has instruments on board. it will look at the chemical composition of the comet and determine if it contains water and the basic chemicals that form the basic building blocks of life. it could determine that comets ended up putting most of the water on the earth and may have seeded the earth with those building blocks of life. if the comets have been shown to do that, it bolsters the theory it could have done it elsewhere in the universe as well. this is very useful, just landing on it and being able to anchor itself as well as the scientific data that are going to come back. >> just to be real clear about this, it took ten years to get there. all of the experiments are going to be transmitted data, right? they aren't collecting samples and taking ten years to come home with them, correct? >> that's correct. all the data will be t

so everybody -- someday it's to be hoped humankind will be able to give an ast mid eroid a litt nudgeo so it doesn't hit the earth. now, the word "comet" is where you have enough water that the gentle heating from the sun causes a tail to form. that's why we love these things. they're made of the same thing as an asteroid, rocks and ice. there's a lot of water ice in the solar system so that's why people have proposed flying out to asteroids, harvesting the water, using electricity from solar panels making rocket fuel and flying around. these are all extraordinary ideas but the longest journey starts with a single step. >> if this is a step, what's the next one? once the landing happens, then what? >> well, the next step -- then we'll find out more about the comet itself. so you see there's an expression we love. is it a solid object that bruce willis' character would have encountered? >> now you're speaking my language. >> or it is a rubble pile? pile? it's in outer space, it's a thing, a cluster. we want to learn more about how these things travel and what holds them together. if we

this is a fascinating glimpse at something that has intrigued humanity since the dawn of humankind.omet, we've looked up in the sky and seen these mudgy stars and thought they were bad omens or good omens or something. they are a fascinating collection to our ancestral past literally billions of years ago pulled out of the freezer and brought to us. in this case we can open the freezer door and pull out things and see what's inside. this is what we'll find out in the next few days we hope. >> and fred pleitgen who is in germany at mission control where they have been ecstatic for the last 25 minutes or so. fred, we don't have pictures from the surface of the comet but they have been sending back pictures since the philae probe released from rosetta about seven hours ago. i don't know if we have any image there is but we got a vanity image that was released by the european space agency. let's put this up. this was a tweet that came out from them. you can see touchdown on 67-p. i don't believe that's a real picture. maybe it is, fred, but you can tell they're very, very excited. >> th

i would say that somehow we would have to link the research to benefits to humankind. we did that in the 1950's in terms of research for the vast segments of the developing world. i think there has been a feeling that the research agenda over the last 20 or 30 years has not been as innovative and supple and productive in the public sector. in the private sector, they have been able to produce certain benefits to crops and other things that people are found beneficial. you are going to drive people. some people said it is terrible for the nih to get so much research and agriculture does not. you have cancer or heart disease or alzheimer's, you can pretty much understand why the nih gets more research because it impacts people's lives so directly. i think we have to do a better job of that and relating the both to agriculture but also to the consuming public. but at leasto do there is the growing recognition led by you and others, this trend does need to change. we will probably never get the nih but we need to be on the upside rather than a downside. the story needs to

in addition you to take into account the humankind costs, the fact there was this collateral damage. the result is when you think about targeting in these kinds of complex, it's actually more humanitarian differently than it is on our conventional understanding of just kill and capture. the first lesson is that in these kinds of conflicts, strategy and human our online. they are not in conflict. the second thing i think is interesting about these conflicts is the transition from war to peace. the convention when we think about this is there is a clean break between war and peace. you fight the war, the war is over and then there's the peace. we talk about post-conflict reconstruction. post-conflict justice. the conflict is apparently over so you think about world war i or world war ii. we can pin point days when things were signed in old warson out on ships often, that kind of thing. but think about our current wars. so did the iraq war in when the constitution was written, when saddam was tried? day began with the search? did indian 2011, 2012? is it over now? afghanistan, the sovie

what is really important about 1989, 1990, 1991 as symbolic demonstrated to all humankind that the communist model was no longer a viable alternative way of life. yes, that is important as giving rise to the importance of islamism. the destruction of communism as a framework for ordering the political economies of societies is really important everywhere. it is not just the events in berlin, but it is also obviously the trajectory and the reconfiguration of the political economy of china during these years. these things intersect. on the whole, you have two huge transformations -- the transformation in the structure of power in the international system, transformation in the perception of the viability's a certain political economies. those are huge changes that i think helped to define the 20th century. >> can i say one thing really quick? just briefly, if i understood your question, you said, what about the historiography would i like to change -- what i would like to change is there's a lot of writing about the cold war and the end of the cold war that talks about europe without talking a

may no that the african slave trade was one of the most profitable enterprises in the history of humankind which is one of the reasons why it lasted hundreds of years and has been so difficult to erase the aftermath that still haunts us. that is to say, some of the profits could amount to 1700%. 1700 percent. you invest $1 get 1700 back. i'm sure many of you have lived in the united states long enough to no that their are those who would sell there firstborn child for a 1700 percent profit, let alone some africans they knew nothing about and did not no. so with the onset of free trade in africans and deregulation of the african slave trade you had a tremendous increase in the number of african spot across the atlantic, the late 16 hundreds and early 17 hundreds. this also leads to work that kirby and historians, walter rodney, diana talk about in terms of the origins or the takeoff of the system we now know as capitalism. that that is to say, the african slave trade formed the spine and the backbone for the takeoff of the system we now know as capitalism. when you have brought all of the a

it's a great question, and i would say that somehow we've got to link the research to benefits to humankind. we did that in the 1950s in terms of the research that vast segments of the developing world were never done before. tlink there has been a feeling that the research agenda over the last 20 or 30 years hasn't been as innovative and as supple and as necessarily productive, at least in the public sector. in the private sector, they've been able to produce certain benefits to crops and other things that i think people have found very beneficial. the issues -- you're ultimately going to drive people with issues that affect their gut. some people said it's terrible that the nih gets so much research and agriculture doesn't. i said, well, if you've got cancer, or alzheimer's, you understand why it gets more research than agriculture because it impacts people's lives so directly. and i think we have to do a better job of that in relating the benefits both to agriculture but also to the consuming public. and it's tough to do, but at least there's the growing recognition led by you and others

site, not just about the people on the humankind basis but also to see what we could do to build uppolitical opposition within se ri pak as far as the bombing goes, the damage done by saying we're going to bomb and not bombing, damaged the credibility the present. when he said there was a red line that couldn't be crossed because of chemical weapons, and then that line was crossed not once but a dozen or 13 times, the world got the message that the president was in serious. we need instead is going to take action and then he said he wasn't going to take action, the world got that message and it wasn't just a side who got the message. putin got the message. kim jong-un got the message as well. having said that, you don't know what would've happened if we would have struck a blow. is very well possible that no one would've had more leverage with assad to reach a chemical weapons deal that assad might be weakened. the president's own chief intelligence adviser in testifying in front of the congress a couple of months ago said -- bashar al-assad has gotten stronger, a stronger assad is

. >> so just keep in mind that space exploration really is, an extraordinary thing that humankind does. there's two questions, everybody, that get us all. where did we come from? and are we alone in the universe? >> help us understand how landing on a comet will help us understand where we came from? >> the comet is made of primordial stuff. the stuff of the earliest solar system. and learning more about that material informs more about what the early earth was like. so there's a lot more water in the solar system than used to be presumed. and by water, i'm talking about water ice. and ice. and so the earth was probably forming and a bunch of comets came in and put water there. what kind of water watt was it? was it salty, ammonia-full water? were there amino acids which seem to form like crazy in the solar system and they hooked up and here we all are? these are cool questions. we chip away at this. and we are, it's very reasonable that we are the first generation of humans to find out if life is common in the solar system or common in the universe or just extremely rare. which either
