@yogthos Also in 1953 - and this was most likely the true motivation for the poster - after all, these bombs were миролюбивые!

@kravietz I'll go out on a limb here, but maybe they just didn't want the same thing that happened in Hiroshima and Nagasaki happening to them. When you're dealing with a superpower that's already shown willingness to mass murder people with nuclear weapons what other options do you suggest?
Japanese Emperor (1944):
"We can no longer direct the war with any hope of success. The only course left is for Japan's one hundred million people to sacrifice their lives by charging the enemy to make them lose the will to fight."
This may sound cynical, but even though the bombs killed hundreds of thousands, they saved millions of Japanes people who would be otherwise sacrificed by the Emperor.
By the way, US was *not* at war with USSR, as it was with Japan. US and USSR were actually Allies!
Also, did you realize USSR invaded Japan-held Manchuria on 9 August, the same day US dropped the bomb on Nagasaki?
@kravietz ah yes that's exactly the same thing as nuking cities.
By 1953 US and USSR most certainly were not allies, and US already demonstrated their level of depravity in Japan.
