Name 3 ways that the war had become a global war – as opposed to simply a ground war fought in europe.

This question can refer to either first or second World Wars. In both cases it happened that 1) the immigrans and refugees went to other countries - such as Latin America, which affected those countries 2) almost all countries were affiliated with one or the other side - sending them ams for example 3) many other countries send their men to fight in those wars, which is why many Canadians and US-Americans fought and died in Europe

If u can translate that to english i will surely you!
