Yes, US imperialism is responsible for much of what is going on in the middle east. I'm not going to pretend to know enough about those conflicts to answer your question, but I'm not exactly sure how it's relevant. But as a general rule, yeah the US should fuck off and stop interfering in other countries. It never helps and it's never truly motivated by selfless goals. America does not support Israel because Israel is "good", they support Israel because it's their proxy base in the middle east. Hence why not even Democrats give a fuck that their "closest ally" is murdering children daily.

The US should absolutely stop funding Israel and Israel should immediately withdraw from the Gaza, the West Bank, and its illegal settlements. Not sure what you expected me to say.
