In general principle, I am against us getting involved in any more Mideast messes. We do not need to police the world. Egypt is an impossible mess. Our coming in there would make it worse. And how are we going to topple the regime in Syria without taking the side of a faction which might be just as bad?
Democracy in Iraq? Afghanistan? What a joke. We did not spread democracy to those two tormented lands; we mere opened the door for a different form of fanaticism.
How do we spread democracy? By being a better democracy ourselves, by not giving in to fear of fanatics and handing over our liberties in exchange for a false sense of safety. Lead by example, not force. Force hasn't worked in the past, what makes us think it will work now?
