he actually helped develop the high explosive lens that was integral to the nagasaki bomb to directing the explosives inward. he also provided sketches and descriptions of not only the lens but also some of the dynamics of creating these weapons systems to the soviet union. he gave a list of personnel to the soviets that could potentially be recruited later on by soviet intelligence. really what he comes down to somebody he is the real supplement to fuchs. he he, fuchs, was the one with the real ideas and providing the real physics behind the atomic bomb whereas greenglass could provide the actual mechanics behind building these weapons systems. so together they provided the soviets with a lot of really important information. so we flou actually so some of the greenglass sketches that he provided to the soviets during this time because of the end of the cold war and declassification of some of this. this first sketch is actually the sketch of the fat man boy the plutonium bomb, they used implosion to create a nuclear clan reaction. in the explosive lenses are the things on the outside

it was a modified b-29 the same type of bomber used to drop bombs in hiroshima and nagasaki. this was modified to take air samples around the world to try to find out if there are any fissfis fission products in the air. this discovered the bomb test days after it was done by picking up excess radiation, excess fission byproducts as it flew a racetrack pattern in the pacific ocean. immediately the united states got this information. secretary of defense lewis johnson didn't believe it at first. he couldn't come to grips with the fact the soviet union had developed the bomb long before anyone assumed they would do so. truman also could not believe that the soviets were now a nuclear power. he very famously said "i couldn't understand how "those asiatics were able to match what we had done so quickly." after 90% of u.s. atomic physicists looked at the data brought back by this one flight, they concluded, without any real equivocation, yes, the soviet union had in fact detonated their first atomic bomb. so truman had no choice but to accept this and to announce to the american p

also said this year marks the 70th anniversary of the atomic bombings of the cities hiroshima and nagasaki. he stressed that japan attaches great importance to the control and nonproliferation of nuclear weapons. abe urged israel to join the nuclear non-proliferation treaty and quickly ratified the comprehensive nuclear test ban treaty. before the news conference abe laid a wreath at the yad vashem holocaust memorial in jerusalem. he pledged to contribute to world peace so as not to repeat the tragedies of war. the memorial is dedicated to the 6 million jews who died in concentration camps during world war ii. abe signed a book to express sympathy for the victims. >> translator: i declare my determination never to allow such tragedies to happen again in the year marking the 70th anniversary of the end of world war ii and the liberation of auschwitz. >> abe said people must continue to strive for a world free of discrimination and war where human rights are protected. he said japan is determined to contribute even more proactively to world peace and stability. >>> japan's defense minister h

deemed so brutal and so incendiary when it arrived in japan, which was right after hiroshima and nagasaki said we're not going to show this. it's, you know we've already made the point, we don't need to do this in a movie. >> mark harris, while we're talking about director frank capra, i want to ask you about "private snafu." 26 cartoons, we should point out, not designed for children. what's the story behind it? >> right. they weren't designed for chirp, and in fact, they weren't designed for adult civilians either. these were adults-only cartoons that were meant to be shown to servicemen. and they were technically instructional films. and that private snafu, who is this kind of screw-up private, as you'll see he looks a lot like elmer fudd. because he derives from early drawings of elmer fudd, who was just being created as a character. he was meant to give soldiers instructions on everything from the danger of consorting with prostitutes in foreign countries to how to protect yourself against malaria, to the importance of not gossiping or passing along secrets. and usually these five mi

boosted weapons where you go from the nagasaki bomb equivalent of 20 kilotons of tnt and then hundredsnd then the hydrogen bomb of the early 1950s where you had millions of tons of tnt. he was in all these conversations. he was part of these conversations and all of them are leak to the soviet union. then you have david green glass. he gets a lot of bad rap because he was the primary witness against the rosenburgs and he lied about a lot of things he was saying. it's a good possibility that ethyl rosenburg was executed because of his lies. that doesn't under cut his role. you have to make a physical product. he was part of this process. he he helped and provided steches and descriptions of not only the lens but the dynamics of creating the systems to the soviet union. and really what he comes down to is he is the supplement. he was providing the real physics and physics and they provided a lot of important information and we now have the sketches with the end of the cold war. this first sketch is the sketch of the fat man boy, the bomb and the implosion to create a nuclear chain reacti

atomic bomb was whether or not it would work and that question had been answered by hiroshima and nagasaki the man doing the quote is glenn seaborg. discoverer of plutonium, the manhattan project scientist, he is somebody who knows. there is a longer quote i'm not going to read all of, but this is from a man who was the chief scientist for what is called the american mission to discover what the german atomic bomb program was doing -- he understood scientific intelligence. so this is after the bomb, right after the soviet bomb came out. and said, the recent revelations of early leaks of atomic revelation to russia reflect a state of mind which should fill each of us with grave concern. the general impression seems to be russia has a bomb, therefore someone must have given her our secrets. we skip down to the bottom. by all means let us understand clearly and admit openly that the russians constructed their bomb all by themselves without any help from us or from captured germans. it is very wrong to underestimate one's adversaries. the question is, did they get the bomb because of the spies

we have world war ii the crew of the enola gay dropped the atomic bomb on hiroshima and nagasaki. they probably had -- there's no doubt they have psychological problems the rest of their lives, killing thousands of innocent people. however, those actions probably saved millions of lives in an invasion of japan. we also did pretty much the same thing in germany, dropping for the forous bombs on dresden, which created firestorms killed tens of thousands of innocent -- i say innocent, but i'm talking about civilians, women and children. that is war. that's why we have to -- that is the last alternative that we should at on the scale. host: all right, richard, we're going to leave it there. thanks for calling in. from "the hill," u.s. moving personnel out of yemen. the u.s. will remove additional personnel from yemen and heighten security concerns amid -- amid heightened security concerns after shiite rebels forced the resignation of the country's president. coming up next is ambassador marc ginsberg, a middle east expert and will be talking about what's the situation in yemen, how it
