When the USA joined the war it was already clear the axis had lost.
While I agree that that it was the Soviet and Chinese people that absorbed the greatest part of the Axis' powers warmaking ability (which western historians are apt to ignore), it's not true that the Axis had already lost the war by 1941. It's accurate to say that the US joined the war at a moment when the Axis forces had hopelessly overstretched themselves.
No... they haven't. Colonialism is not the past... it's the present. And the Netherlands still benefit from it to this very day.
