there were countries in South America in the war. Brazil was one such country.
I don’t know about other South American countries.
I wouldn’t call Portugal an European power, they never had a significant population. Same for Switzerland.
Spain was completely destroyed just before world war 2 during a civil war
Most of Asia and Africa had been put under European control before world war 2, which actually was one of the reasons there was war: Germans had almost no colonies and wanted to expand
Turkey had lost world war 1 a few years back (Ottoman Empire)
