iran is a russian protectorate. they don't say that in the news, but there are russian defense systems protecting iran, and any sort of substantive attack on iran would result in russia coming to their defense. if trump is trying to make a deal with putin, there is some possibility it could involve turning on or cutting out israel. trump himself, who is somewhat of a closet nazi, would not be that concerned about that. his party - and his base - would be.
i don't want to speculate too much.
