They can be true hypocrites at times (spoilers)

they're not the ones who made that decision, for starters. also, it's a part of history and would constitute a humongous change that would screw up the timeline in a major way. since new york wasn't supposed to be nuked originally, and the war continued on for several more years, i think they're allowed to be shocked at the millions of extra dead

It's no different than Christians passing judgement on Muslim's for the actions of extremist when Christians have also murdered people under the cloak of religion for years, or a black person being who moans about the racism towards black people but ignores the equal amount of racism shown by some black people at the same time.

Americans will always think an attack on America is uncalled for and evil, as will us Brits towards an attack on us, as will the French, the Irish, Pakistani, Indian, Chinese or Bulgarians and so on.

Plus as an established event their worlds history a bombings in japan are a matter or fact to them regardless of the unfortunate casualties, where as this was a attack never meant to happen by the NAZIS off all people on their country, it makes sense they would be appalled, plus the nuking of NY actually caused 12,000,000 extra lives to be lost and the war prolonged by two years, so it was actually on both sides a worse outcome.

America held nuclear supremacy over the world for many many years, and did not abuse that power. Japan would have burned any opposing nations to a cinder. Remember, this is the nation that would publish 'beheading' contests in their newspapers. For that matter, there is not many nations in the world that would not have abused that power.

Hating the USA is very trendy. But I'm glad they held this power first.

except even the Japanese acknowledge that the causalities of military and civilian populations would have been significantly higher had the US not dropped the bombs thus ending the war.
