There are facts that most Americans ignore...
We are now the largest superpower on Earth. China is coming up fast but still lags.
We can afford to operate a sophisticated intel network which includes aerial recon, satellites, electronics and human agents. Plus a large naval and air force presence.
The US seldom intervenes in other countries soley for "humanitarian" interests. The US tends to overlook countries with no strategic or economic value to the US.
The U.S. selectively backs despots, juntas and dictators when they are friendly(er) to US interests than their counterparts. Some of these people are nasty to their countrymen.
Sometimes, when political winds shift, U.S. intelligence may betray rebel causes within a country to court an existing government. This is frowned upon by those same rebel groups and they remember it when they get in power.
Also, by the same token, if a leader becomes a liability in either internal or international politics, the US political machine can stop supporting a government almost at a whim. This does not endear us to anyone.
In some countries, the US may play both sides. Rebels may get arms and equipment, the government gets aircraft or money to fight the rebels. Government contractors are pleased. The citizens of that other country are not.
Sure, our "meddling" in the region has stoked some bitter enemies and stirred the ire of a lot of people. George Washington warned us of "foreign entanglements" of this sort and others for good reason. It seems Ron Paul would prefer to follow this logic, difficult as it may be in today's world.
Sadly, the rebels who condemn the US find it almost impossible, once they gain power, to back away from the condemnations. Even if US aid would ease the suffering of their people or provide a benefit for them. This leads them to ally themselves with our opposites, China, Russia, etc., which makes further spying and "meddling" a certainty.
Religious fundamentalists, of any stripe, (imho) are like the Puritans - they're desperately worried that someone, somewhere, is actually having fun. But when they're in power, they use their religion to force people to behave in a manner which they think is "proper", to the exclusion of all else. And Islam, with its bloody history of convert or die is particularly violent and particularly un-suited to be a part of any government.
