What are you expecting when you're physically in another country attempting to annex it?

The only reason I suspect Iranian proxies are not doing the same in the US is right now the US is just Trump in Iran with 2/3rds of the country not supporting him. The day a bunch of civilians bite it partying in Miami, that calculation changes.

The US is "guilty" of materially supporting Ukraine in a bid to defend itself. The US isn't mad at Russia or China for doing the same for Iran as this is all... fairly normal in geo politics.
