The US had been an imperialist power in the Pacific and on Japan beginning in the 1850’s with the
expedition of Commodore Matthew Perry. It brutally conquered the Philippines, in Japan's backyard, at the turn of the century and had military bases there ever since. The US wouldn’t let Japan get their oil from anyplace in their neighborhood, it had to be purchased from the US, and they wanted this to change. Bombing Pearl Harbor was a fooling way of going about it, but it was only a military target, and never made them a threat to the US, contrary to the war propaganda, that to this day is still believed by a great many.
If the Pearl Harbor bombing justified the US decimating Japan, as the US did, then half or more of the world is justified in violently responding to the US in any way or manner they choose, because the US, and its century plus year old every expanding global empire has aggressed on them, in one way or another, which is far more than Japan did to the US.
And it’s no accident that China was taken over by communists a few years after the US conquered and occupied Japan.
