Rand Paul asked Rubio what would happen if the shoe was on the other foot. Every US President from Truman onwards is a war criminal.

The people of the US mostly wouldn’t like it the people of VZ mostly did and consider Maduro a thug who lost and stayed in power not their president. Ideologies like Paul have trouble with exceptions to their world view.
I never liked the Paul's and their opinions, but I must say that they usually speak according to their principles, rather than make up principles to fit what they want to happen.
To me, that's the distinction between political opponents I can respect, and, well, whatever we're seeing now.
