Agreed, that's a redline for me. American boots on the ground in some sort of invasion. But some airstrikes, some covert (while openly leaked to the new york times) cia dudes, fomenting a coup without putting our troops in harm's way? That isn't ideal, but it's not exactly war in MENA is it? I'm more okay with us fucking around in our own backyard overturning faggots like Maduro that make it harder for us to bring Russia to heel. I'm still uneasy about it, and if it does turn into a vietnam sort of thing; CIA operators morphing into a full on military troops on foreign soil, i'm going to be furious.
That said, the Iran stuff was flawless, and Trump showed he was willing to wreck your shit if you fuck around. I don't mind it, as what it was seemed to be Trump showing he will fuck you up, and that option is on the table. you do that shit once, and do it as well as we did, you shouldn't have to prove that lesson twice.
