They are teaming up with them because, apparently, the lefts Trump-hatred trumps their anti-war principles.
It's pretty plain to anyone who is paying attention. Never thought I'd see the day. I pointed out the hypocrisy the other day when Trump removed our support for the Syrian rebels/terrorists. It means we are no longer trying to topple a secular Middle East dictator [you know, like you never tire of reminding us about Iraq].
It makes Trump the anti-Bush, anti-neocon [why do you think neocons like McCain loathe Trump---why do you think McCain was so hot to trot about the Piss Dossier?] and not a peep out of people like you.
All they/you want to do is talk about is Russia.
