Modernization? Do you think it's likely he'll be more interventionist than the Obama years? It's hard to imagine that, but of course it's possible, the question is is it likely?

Obama was actually very restrained in foreign policy - far moreso than Hillary Clinton would've been, for example, and also moreso than Bush Jr., Reagan, or even Bill Clinton. He's relied largely on drone strikes and covert assistance, while the other presidents mentioned actually invaded other countries. Obama's own national security staff criticized him heavily for this.

Anyway, I didn't mention political parties in my original post, and AFAIC trying to make this partisan is just projection. There are hawks on both sides of the aisle: the Democrats are milking Russophobia for all it's worth and seem to want to start a new Cold War, the Trumpists see the world as a clash of civilizations between the Judeochristian West and Islam, and old-line Republicans like McCain and Graham are very skeptical of Iran and China.

I don't mean to take it into the ideological realm. I can't disagree with what you said, except the money spent on foreign wars/intervention was pretty ramped up during Bush II and Obama.
