Yep, we're back at it again. Latin Americans have a name for it: "Imperialismo Americano".
In English, "America imperialism" is a phrase for political propaganda, like "woke", "freedom", etc. You can argue if it makes sense or not. You can disagree if it exists. It is an opinion.
In Latin America it is a fact of life, like rain and sunshine. It is there, everyone knows. No one denies it.
And how did America benefit? They didnt. But you know who did? Israel.
The fundies, who actually believe they're paving the way for the Second Coming.
American oil interests, for whom the Middle East is their primary competitor.
And, naively, there are people who didn't benefit, but believed the US' (oligarchs') interests would be furthered.
