Its is the chinesse communist party that embraced capitalism, not the people. The party enforces very clear communist laws on society, where they constantly tell you what you have to do and what not (if you don't follow, you will "dissapear"), with the chinese system of good citizen system being the last straw on the life of the people over there.
So technically China still stands as a communist regime, and one of the worse. I don't need to remind anyone that Mao Zedong still holds the record as the biggest murdered in history, closely followed by Stalin, both of them communist systems.
About the germans. They don't have to apologize because it was the nazi that controlled everything. They defiled the honour of the german army, and condemned them to be having to be forever apologizing, something I dissaprove, because one thing was the nazis, and another different one the german army. They also tried to honourable "remove" Hitler from power, always ending in failure. Still, I have to be thankful to the nazis for helping us winning the war against the communits scourge here, but they didn't win the war in the end. It was us. What I'm not going to ever forgive them is for the Jew and other minorities massacres. There's no hell where nazis can be properly punished for that, and that sours me too. Yeah the people of Germany were also responsible for what happened since they voted them, but in the end they still paid for their mistake, and were bombed to hell by allies. Still, it is necessary to undertand the scenario and circumstances that took the nazis to the power via people's vote. You cannot blame the people so..., lightly sometimes.
About Japan. They also paid the price for their mistakes and violence towards others, specially for the massacres on China. Do you really think the americans would be dumb enough to invade the main island after histerical losses they got in the many "skirmishes" on those many islands?, of course there weren't, and they did the necessary to end the war once and for all, saving the lives of maybe millions of their soldiers, and I approve that too. Was it terrible what happened to the humble citizens of those two damned cities?, of course, but war is war. Did you know that the americans were to launch a third strike directly above the emperor's palace?, they quickly raised the white flag, which they didn't while Hirosima and Nagasaki people were literally disintegrated at a molecular level.
And about the french. The society and system we live today still is the aftermath of ww2, so yes, they should be thanking the american sacrifice at the very least until ww3; and not just the french..
