Americans consistently vote for less war and they consistently get more war. If they voted for more war I’m pretty sure they would still get more war. I think blaming the American public for these wars is a deflection from the actual mechanisms that instigate them. We are more governed by blackmail than we are by voters.
I do wish there was even more resistance though, war has been effectively pitched as costless or even as a boon. Perhaps if this war bites there will be more resistance to future wars. At the very least the Iran war being such a disaster may have saved us from a more costly war with China - which the US was and in some ways still is gearing up for.
