To be fair arguably there is no other country in the world which benefited as much economically from its interactions with Nazi Germany and face so little consequences for it.
A less flamebaity response is that the Soviet Union ended up as one of the winners of the second world war. They lost a lot people (Stalin didn't care) but almost all of that was because of Stalin's incompetence (having killed most officers shortly before the war + sent millions to war without proper boots, uniforms, weapons, and ammo).
Israel got an entire country out of it.
