How about "guardian of our own liberties"?

Diana West is " still waiting for a straightforward discussion of what it is we can reasonably expect to win" in Iraq. Given that "42 percent [of Iraqis] think attacks on U.S. forces are acceptable," it sounds like, after five years of trying to help them, our expectations ought to be on the modest side.

As the man once said, we should be the friends of liberty everywhere, but the guardians only of our own. Given the widespread attitude above, the idea of taking care of only our own liberty begins to have a lot of appeal to me.

The freeloading Europeans help me to get there, too. They were quite happy to have us pick up the tab for so much of the military defense of Europe and keeping the peace elsewhere in the world while they loaded up their citizens with social welfare goodies. Then they looked down their noses at us as the "world's policemen" while grandstanding as havens of enlightenment.

Something like that.
