How much liberty do with want to give up for a false sense of security?

The idea of foreign policy realism, I think, fits more neatly with President Trump. And with John McCain, the neoconservative label of let's make the world safe for democracy and we're going to topple every regime hasn't worked.

Currently, the United States has troops in dozens of countries and is actively fighting in Iraq, Syria, Libya, and Yemen (with the occasional drone strike in Pakistan).
