Saying they're the party of complacency isn't really accurate. Obama may not have started any new wars (although there's an argument to be made that his operations in Somalia represented a new, unsanctioned war front), but he didn't get us out of Afghanistan, kept joint military operations going in Iraq, and created a massive, unaccountable robot assassination program that killed thousands of people, including U.S. citizens. That's wasn't an act of complacency, it was expansion.

To me, the difference in Democrats' and Republicans' positions on military use can be best summerize by how Obama and Trump reported drone deaths. Obama reclassified every adult male in a target zone as an enemy combatant so that he could artificially lower the number of civilian casualties. Trump just stopped reporting the numbers. One is obviously better than the other, but I wouldn't call either anti-war.

But let's say you're right; the Democrats are mostly anti-war, but they're too complacent with the status quo, and Trump voters are all idiots who can't tell the difference. What are we gonna do about it? 51% of the electorate went to Trump. Are the Democrats going to stand up to the military industrial complex to make their anti-war stance so clear even an idiot could see it? Or are they just gonna lose forever?
