US sucking up to Israel wasn't a thing until the early 1960s when they got rid of JFK. Every president after Kennedy made exceptions for them.
What makes you think US is sucking upto Israel?
Why you all think Trump is dragging US into war "NOW"?
If you look at recent events, then I am quite confident Israel had been a pawn to US in this.
US regardless of which political ideology forms the government, always saw Iran Nuclear program a massive threat.
If you look into recent events - shadow war in the middle East, deal with Yemen, Trump pressuring Iran for nuclear deal and Trump previously saying to stirke nuclear sites in Iran if deal is not done, it's clear Israel struck Iran with green signal from Trump beforehand.
The act of aggression from Israel come across as an act done both by US and Israel to coerce Iran into submission to have nuclear deal the way US wants.
A non nuclear Iran favors the West, Israel, and even some Arab nations.
Trump recent comment' further reflects that he will use force to put pressure on Iran to have a deal......
Having that said, Iran has every right to defend against this.
