> the US predictably got even wealthier than it previously was

If you just look at the economic indicators, then it did. Certainly way better than the "no intervention" counterfactual would have gone. People do not like it when all the ATMs stop working.

There is a lot of discourse to be had as to why people aren't feeling that personally.

> killing people in Iraq because Muslims, amirite? All those bombs cost a bomb.

Sadly there is/was massive bipartisan support for this bullshit. Including from the public. I note from a chronology perspective that most of the money in Iraq was spent/lost/wasted before 2008.
