This shows as horrible any War is, specially when we talking about a World War!

After Hiroshima anyone knew Japan was Game Over, nevertheless some people wanted to murder so much people in Nagasaki too and used this chance to test an atomic bomb with plutonium to compare the effect with the first one in Hiroshima where they used uranium.

How much hatred is necessary to do this???I can't answer this, but it's good to see you start to thematize this theme, because nobody should forget "what" War means before humans make wrong decisions, specially when we think about the fusion bomb in this time, which is much pore powerful as a lot of atom bombs which were used earlier.

By the way, in the second part of Terminator they made a good job by to simulate the explosion of a fusion bomb, although that's just my opinion of course, an opinion of a layman by this topic.
