first i want to get up this building to get a panoramic view of potsdam up lots. in europe's fastest elevator takes you up to the twenty fourth floor in twenty seconds flacks. one hundred meters up you can see that potsdamer platz is at the heart of the city there you've got the right start building the brandenburg gate the full armonica. that you're gonna slide secure planks and two nice recognize the t.v. tower. in the back around that cafe is the perfect place to take a little break and enjoy the view. during the golden twenties this was a place to be there are luxury hotels fashionable restaurants movie houses and theaters but during world war two it was almost entirely destroyed and it's so close to half a century to rebuild it. this is part of some other plots as we now know it. back in the one nine hundred twenty s. this intersection was already a hive of activity until bombs pounded into rubble in the second world war. then it became a wasteland in the middle of a divided city. when the berlin wall went up in one thousand nine hundred sixty one would sum u

and it really came down to potsdam. truman had to make this decision.is an ultimatum to japan saying "you need to surrender or we're going to do something really, really dark." the language is clear in retrospect that they are talking about the bomb, but of course it was a secret. now, the term unconditional surrender is in that document. we know that truman was reading the ultradocuments. we were intercepting japan's secret documents and we have them. truman knew exactly what the japanese were thinking. they were thinking that unconditional surrender meant we were going to incarcerate and execute the emperor. if unconditional surrender were in the document we needed japan would refuse to surrender and we bomb.drop the a lot of advisors said let's drop the word unconditional. it is amazing to think that these two bombings -- we could put historians are on the table and debate this for hours -- but it is probable if we had removed unconditional from the ultimatum, japan probably would have surrendered. burns was the loudest voice saying we can't do that

truman leaves sailing across -- , potsdam. truman is dying to find out, he doesn't know when the mission is going to be flown. he knows we will drop the bomb but we don't know when, because it is military secret. >> why wouldn't you know? >> that is the level of security. >> did he have a say? >> no. the decision to when and where was up to the military. truman had very little to do with the decision, certainly no decision on when it would be dropped. he wanted it to be dropped after he left potsdam. >> he gave permission. >> correct. and we have that documentation, too. i found these wonderful documents where one of his aides sends these messages to the white house, asking for information about the manhattan project, which would have been a grave violation of secrecy, of security, and it was so secret that the military map room, where all the military documents were sent, they cabled back to the ship saying we don't even know what this manhattan project is stop them the aide writes back saying don't look into this. they reali

every year in february the theater on potsdamer platz turns into the belly not the pop. stars who have already graced the red carpet here in berlin include catherine deneuve. and ella b. cruz. you jacqueline. robert pattinson. berlin love celebrities and they love. film buffs are already on rolling their sleeping bags to make sure they can get tickets some tickets are sold online but most are available at the box office three days before each screening that means. radio was free i was but i was at the front of the key role and has its own feel. it has its own energy and so that also gets translated into the film festival it's a very different cinema experience it's not about popcorn but about real film buffs coming together. speaking of popcorn one of the many berlin film festival sections is colin airy cinema first a movie featuring food is screened and afterwords gourmet chefs serve a menu inspired by. their best two straight laced for you it's off to the bradley not a party they take place all over the city. this is where the industry insiders meet it's all about seei

he's at potsdam. now, we know -- i mean, we have all the documentation, so we're very aware of what he knew, what the other people around him knew and what was being communicated to him. this document here, it's july 25th, we know he pretty much made actual decision and gave the orders on july 24th, which happens to be my birthday, and this is his diary on july 25th. the operative sentence here is "the weapon is to be used against japan between now and august 10th." "i have told the secretary of war, mr. stimson, to use it so military objectives and soldiers and sailors are the target and not women and children." now, as writers and historians and thinkers and all of us here, there are always pieces of the puzzles missing. there's always pieces that we have to interpret. and how do we interpret those moments? you know, some people are going to say, well, there's a god. and some people say, well, i'm an atheist, and are those decisions hard wired into us? do we think of those things because of who we a

he wanted it to be dropped after he left potsdam. brian: so he gave permission -- a.j.: he did.e have the documentation, too, which is interesting. i found these wonderful documents where one of his aides sends a message to the white house asking for information about the manhattan project, which would have been a great violation of secrecy, security. it was so secret that the military map room, the map room were all of the military theyents were sent -- cabled back to the ship sank, we don't even know what this manhattan project is. truman's eight aboard the ship rights back and says, you know what? please don't look into this. they realized they have made a mistake even by inquiring about the bomb. so it's not until august 5 aboard the boat, august 16 japan, august 5 aboard the boat when truman learns -- again he is at lunch -- that the bomb has been dropped. brian: here is august 6, video harry truman on the ship. there is a porthole off to his left, announcing to the american people -- it's not live of course, but announcing to the american people, i assume on film about the

now we get to potsdam. truman now? president. and he has no experience in international relations. he's never met stalin. never met churchhill. and three months into his presidency. he doesn't know if the bomb is going to work yet. he has to sail across the country -- i mean, the atlantic. and the war in europe was over. so the whole world knows teheran and yalta there were secret conferences. the whole world knows this is going on. and the american people are expecteding their new president to bring something home to them. there's a tremendous amount of pressure. truman is its at the negotiating table to map out the future of the world. >> when truman became president, president truman did the oath, how much did he know about what was going on in the war? >> the way -- let me frame it to you this way. he knew, he was an expert on the home front. he knew as much as anybody what was going on in the production of the military, the home front effort to win the war. in terms of the international emergency, he probably didn't know all that much more than your average person who studied
