I think a lot of people are being isolationist which is pretty niave and indefensable position this day and age. But others just dont believe that Israel is telling the truth about the nuclear threat and for good reason. The Iraq invasion and the lies told to justify that were so criminal and spectacular that millennials and older just dont want to fall for that again. A country hating us or conducting themselves domestically in a way we dont like shouldn't justify a war. I don't know what to believe anymore either. If Iran is as close as Israel says they are to building a nuke, then fine I say its justified. If not, then this is Iraq invasion level bad all over again.
