The TSAR bomb was P.R. ploy. It was a Hydrogen bomb. H bombs are scaleable. Its no harder to build a big one than a small one. There is a lot of good stuff to read about the TSAR bomb. It actually only yielded about 60% of what it was specked to do. The builder scaled down the reaction because he knew that if he delivered the full tonnage asked for he would do great damage to the USSR with fallout.We could have tested one bigger than the TSAR, but there was no point. Russia was just blustering.
Being there gives you wonderful perspective of one side of a historical event. History gives you both sides. Recently released Soviet history shows us that Khrushchev did not respect Kennedy. He saw him as weak and indecisive. Kennedy was very passive and appeasing in a conference they had. Khrushchev smelled weakness. Kennedy demonstrating weakness was the immediate cause of the missile crisis. We learn that from USSR history.
That's a subject for its own thread.
