Typical American Bulldung propaganda. Unless American atomic first strike against Japanese cities in WW2 is recognized as genocide and the United Snakes is dismembered into tiny independent statelets as means of accountability, then any use of nukes by Russia against targets in Ukraine and the US is legitimately justified under international norms and traditions as enshrined by the US and its NATzO vassals.
During the war, very few, if any, Chinese had any sympathy for the Japanese on account of being bombed by the USA.
The Chinese knew only too well that the Japanese had inflicted much more suffering in China.
(One of my relatives said that the Japanese surrendered too soon; he wished to see more Japanese cities nuked.)
Under international law at that time, the US atomic bombings were not war crimes.
In fact, the US bombing of Tokyo (night of March 9-10, 1945) was the most destructive air raid in history.
Hamburg, Dresden, and Tokyo were some of the terrible precedents before Hiroshima and Nagasaki.
That said, a significant minority of Americans now believes that the US atomic bombings were unnecessary or wrong.
The USA has a terrible record of racism and imperialism. (Saying that has often got me censored in the USA.)
It's appalling, however, that many writers here gladly allow their obsessive hatred of the USA to help rationalize
a real Russian genocide of the Ukrainian people.
