From libertarian weakness, to conservative.
Libertarianism doesn’t necessarily mean weak foreign policy. Ultimately you can’t have liberty at home without a secure nation. I want the maximum amount of liberty at home, but with a government that’s vigorously defends our interest abroad. What I don’t want is getting involved where we have no national interest. I also agree with Paul here that nation building is moronic and doomed to failure over there.
Thomas Jefferson is a big hero to libertarians, he sent the navy to take out the sultan of Tripoli over attacks on American ships. And without a Declaration of War BTW.
