Do you think America is a force for good?

It's a mixed bag. We do some good things, we do some bad things. Our history of protecting and patrolling trade routes for the last several decades brought a lot of prosperity to a lot of places and enabled global trade and stability that created a significant peaceful period between large powers. That was largely good, but also it was done in our own self interest as well, not altruistically. We've also done a lot of bad, interfering in foreign affairs that sometimes made things worse for some nations, enabling certain dictators and autocrats because it was beneficial for us to have them in place and favorable to us. We've engaged in economic warfare to try to topple democratic governments that we didn't like, often because said governments were socialist and protectionist and didn't allow our wealthy people to exploit their nation's wealth for private gain. That's pretty bad.

So yeah, very mixed bag.
