I agree, that's why I was so surprised when Democrats took the warmongering route.
Clinton and Obama were both more than happy to engage in and escalate military conflicts. There is very little difference between mainstream Rs and Ds there, which is why I occasionally refer to them collectively as the PWPBP (pro-war, probusiness party).
I agree with you and most and most Democrats did as well before they shot on their own values because they don't like Trump.
Supporting military action is a shared value for Rs and Ds.
