Sharp, without the internet, you couldn't troll.
Most valid point thus far.
My biggest question is, why does Egypt apply to us? We need to stop trying to be the police of the world because that's why other countries hate us these days (that and we're Capitalist Pigs).
Most of the countries that hate us are either artifacts of the Cold War, as you mentioned, or angry over our support of Israel. Egypt matters because it will either mean religious takeover and policies arrayed against us and our allies, or a democracy that is less philosophically opposed to our own. Egypt also controls the Suez canal.
Every powerful country uses spies and networks to influence the world in their favor. They use force if they can or if they must. It's simply that, as the only major power right now, our efforts are felt most widely and deeply.
You would favor isolationism. I'm unfamiliar with the merits and drawbacks.
