Beyond what? Protecting our borders?
Of course not. The military should only be used for defense, not for "projecting power."
That's not only libertarian, it's America First.
I guess you're a Neocon in search of monsters to destroy.

So our competition will extend beyond their borders but we/USA will not. Your libertarian ideas only work in a world without war and aggression. Sorry bud but there battles going on for world control. China and Islamic lebensraum top the list. Russia is on this list.
