Funny, the Republicans are quickly becoming the hippie/isolationist left of the 1960s. They're for accommodation with Moscow, retreat from the global stage, and think that the war in Iraq was a war for oil (according to the Republican president).
Trust me, I wish that were the case, but it isn't. Drone strikes, sanctions, etc. are continuing under Trump.
It's not an overnight process and to an extent both parties will always favor some military action. But you cannot deny that Iraq has traumatized the Republicans deeply. I remember the South Carolina Republican debate, where Trump echoed Code Pink rhetoric and won the state a few days later. We've come a long way from Reagan and Bush, where the Republicans were more hawkish.
Also Trump and a wing of the Republicans favor lifting sanctions on Russia while another wing favors keeping them, which is a sea change for the Party. In 2005, this would've been unthinkable. There's a lot of open fissures in the Republicans as they're transitioning to being a less interventionist party.
I don't necessarily see the Republicans resuming their old ways. Maybe a bit under Pence in the future but it seems the Republican base is distinctly turning into the anti-war coalition to an extent.
