We currently have agreeable terms with the Saudis. If we ever do not, guess who is suddenly a dictatorship? Things that are happening now on the quiet will suddenly become atrocities, if it serves our agenda. America was once on excellent terms with Noriega, Saddam Hussein and Kadafi (or however you wish to spell his name, as the media changed it daily). We set them up, enjoying the fruits of the relationship (usually financially), and then, we take them out later when they decide to not play anymore. Karzai or Assad will be the next in a long line of jilted friends turned monsters.
We are on tenuous "friendly" terms with a lot of nations. Each side behaves themselves (on the surface) until it serves them to no longer do so. The Saudi leaders are no angels, nor are our guys. That nation was the home for fringe zealots, just as we surely have spawned misguided individuals. Are the bad guys supported by their home countries? Maybe, maybe not. If so, not every single soul in a region is packing the bombs. To say that we should pummel everyone to dust by association is pure ignorance and no different than the mindset of those we condemn.
Again, we are talking individuals, not entire countries. Why bomb the kid going to the community well for water? Would you send drones upon people praying in a church, temple or mosque? Because they MIGHT someday be a terrorist? Really? Then, I suppose you would take it in stride if somebody killed your child or grandchild on an assumption or preconceived bias about his origin, correct?
It's really not about people, so much as money. The Twin Towers were a symbol of American financial power (and make no mistake, a huge phallic symbol). Taking them down was an insult to our image of supremacy, a cutting down of our huge erection, literally. War can be great for the economy, as it was in the WWII era. But none of our modern conflicts have jumpstarted industry or rebuilt roadways. Korea, Vietnam, Kuwait and Iraq were not the economic boon our leaders had hoped for, except perhaps personally. Our leaders continue to follow that old model in a changed world. Yet, only their business associates reap any benefits.
Modern conflicts have also not gained us respect and friendship. It has made us a target and allowed our own domestic society to decline at the cost of force-feeding the "dream" onto other nations. And now that it has been revealed that we spy on our friends as much as our enemies, who will truly be our friend now? As far as the Middle East, we butted our noses into an area that has seen conflict for thousands of years. Did anyone truly expect this intrusion would not bring about some form of retribution eventually? Have a tall glass of oil. I hope it was worth it.
Knee-jerk reactions to 9/11 brought us the Patriot Act and the clandestine NSA actions. Frankly, I am far more concerned for our personal freedoms at home than I am about some tribal conflict in an area that may have natural resources.
