Conservatism never fails you idiot because conservatism calls for folks to conserve, hold true to what we know works, and to make minimal risk. If THAT is a complete failure, we are in deep doodoo.
If so, then give us examples of how conservatism has actually FAILED in each of those categories!
In other words, the only safe bet in foreign policy is liberalism and progressivism? Jack, have you been back as sniffing that glue again?
Everything not actually destroyed yet by you. A better question is what has Progressives progressed to? I mean other than 50 million useless 3rd world illegal aliens sucking us dry, a 40 trillion dollar national debt, and a national intelligence thanks to left wing policies that now leaves us at around 30th smartest in the world.
