Is the Democratic Party becoming increasingly hawkish?

[Crumpets]

I think that's the wrong metric to use to describe their changing views on foreign policy. At the end of the Bush years, the Democrats were much more accepting of a sort of isolationist-lite foreign policy - one of "bring our troops home and work on our own problems." Trump running on his "America first" platform is really a corrupted version of the same playbook Democrats ran on in 2008, and they have, as a result, had to come up with their own opposing message accordingly. With the Arab Spring and the rise of refugees, the Democrats have shifted their focus more towards "use the strength and influence of the US to help the suffering and ease the burden of countries around the world." Personally, I think this is an improvement, and a generally necessary shift when your country recovers from a recession while others have seen their luck go in the opposite direction.
