I don’t care about whatever argument you’re having. It’s extremely inaccurate to claim Americas entry into ww2 was diplomatically motivated when Japan was taking by military force islands that had been part of an extractive zone contested by them and America. It’s literally two imperial powers low key fighting over their periphery then one goes PISS NUKE INCOMING.
Again, I do not care about whatever argument you’re having. If anything I want you to be able to integrate more information into your understanding of imperialism. It’s really hard for us as westerners to do that when so much of the groundwork of our historical understanding is jingoism and great man and it’s good you’re interrogating your own ideas.
Also you should probably start with the Spanish American war as your American point of entry into imperialism (you say here “global interventionism” but idk wth that means.)
