I sometimes wonder if the U.S. has poured out our blood giving liberty to as much of the world as we could get to (yes, imperfectly, yes of course but—) and have ended up etoliated ourselves. A hundred years ago Spain (for example) was a brutal medieval country; we sent resources and men. Today, Spain is ahead of us in certain liberties and privileges.
Did we give too much? Did we give something essential that we couldn't afford to lose?
I'm absolutely not an isolationist.
What we seem to have given up is the will to uphold our own democracy. Have we?
