Yes, surprising in a "I can't believe this is happening" way, not in a "this was unexpected" way. He made his campaign on ending everything. Diving headfirst into the first conflict he could with 0 understanding is the most expected thing that could've happened.

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.
