If the US had been a super power in the 17th or 18th century you can be certain they would have colonized other countries as well.
Regarding WWI and WWII, Europe has never had the homogeneous culture of big states like the US. Again, wars have been the norm for most of humanity. The current peaceful era is really an anomaly.
It is like the bully who broke both legs and then goes around on crutches and tells everyone how great he is in that he doesn’t beat people up anymore.
Do you think the UK would have given up India if it were not for the devastation of two world wars?
Look at how France fought to keep its colonies in Algeria and Vietnam?
Look at how Germany bullies countries like Greece and Italy and cozies (up until very recently) to Putin.
This is like the pot calling the kettle black.
Europe raped the rest of the world for nearly 500 years: the British Raj, the Belgian Congo, the Opium wars, the race for Africa, Apartheid are but a few examples.
Europe created modern chatel slavery.
Europe started the WWI and WWII.
Europe birthed Nazism and Communism.
Many of the problems we currently face are the result of European meddling: from the Sykes-Picot agreement, to Iran, to African civil wars.
The US has been a far more benign superpower than (collectively) Europe ever was.
UPDATE:
Even racism (scientific racism) is a European invention, mainly to justify why it was good for Europeans to subjugate the rest of the world.
