The ones I know are 'sceptical' to 'cautiously optimistic', with a large point being whether or not there is a push for a significant amount of US troops on the ground. The latter is the main issue.
I think until then, they consider it a 'military intervention' rather than really a foreign war. The US, along with the UK and many other countries, have a long history of being involved in this type of thing. That it rarely goes well hasn't stopped us using the tactic of overwhelming power and death to disrupt other countries towards change, alongside many other tactics that haven't gone well that these governments have used which is why Iran is how it is.
We're talking about whether Trump is right. I would fight like hell for my country if someone decided to lie and cheat and make it his own in the way Trump has. You don't even care. Weird.
We already have that in the UK and have for decades with multiple politicians lying, cheating, and making their own way to benefit themselves over the public. We were boldfaced lied to about Iraq, costing so many lives. We're currently being lied to regularly about the selling off of government data, Palantir, and so on, involving a lot of cheating and making their own way. That none of them have done so with Trump's brash and very visible personality doesn't mean it isn't happening.
The methods both governments use in disclosing this information, whether it's firehose, doublespeak, outright inconsistent lies, and many more are purposefully designed to make people not care - at least not enough to risk much.
And thats before we consider all the state sponsored terrorism coming from iran or the alleged fact that even the Saudi crown prince asking Trump to intervene
Which raises why is the US wanting to dance to the tune of Saudi Arabia - a county well known for violence against their own people and involved in state sponsored terrorism. The US's relationship with Saudi Arabia, a country that has far more firepower and power in the Middle East than Iran, deserves more questioning, not used to explain why the US went forward with this action.
Also, the US did this action with Israel, who also has significantly more firepower than Iran and is known for its state violence. We have significant US politicians openly stating that they prioritise Israel over the US. That's a major problem, some have called it treason, some have called it weakness.
