This may well be true, but it was his stated willingness to ease off on the regime change stuff, and maybe seek better relationships with Russia that had the establishment foaming at the mouth. The same people who were making ridicules accusations of Trump being a Russian agent are now patting him on the back, calling him presidential and asking for more of the same. If he wants an easy ride, he will do more of the same. Whoever is elected is always accountable to The War Party.
Interesting though, that the missile attack in Syria didn't really do much other than act as a therapeutic release for those addicted to that sort of thing and perhaps to give the president some breathing room.
