Your 1. is not the only spark of the process you describe, with considerable accuracy. E.g., the US bent itself all out of shape in Viet Nam and did a lot in Korea, and oil or assets of big US companies were not saved or much at risk or involved. But, yes, some big US companies -- Ike's military- industrial complex -- got big bucks. And in Viet Nam, a lot of oil was burned, and I have long guessed we burned enough oil to enable the power of OPEC. Keeping B-52 bombers in the air 24 x 7 in the 1950s also burned a lot of oil. Part of the US overreactions is that from the President on down, it's easier to play cover thy ass by spending US blood and treasure than to speak the often sad, ambiguous, no good option truth to the American people. E.g., in Viet Nam, nearly no one in public office wanted to open themselves to accusations of "Who lost Viet Nam" as happened with "Who lost China" when Mao took over and drove Chang Kai Shek to Taiwan. We finally gave up in Viet Nam when nearly every young person in the country saw someone die in Viet Nam that they had known in high school and the demonstrations were too big to ignore. Even then, President Ford, at the last moment, tried for another big chunk of cash and supplies to Saigon. Congress didn't go along, but Ford had then tried to put the 'blame' on Congress. In some of the earlier days, say, after the Tonkin Gulf thing, there were only a few voices in Congress warning that we were heading for vast disasters with half-vast reasons. But, we should be able just to say no to absurd foreign adventures and hysterical, ineffective overreactions at home; lot's of other countries do: E.g., in Afghanistan, the EU countries mostly stay out of harm's way. In Gulf War I, there was a fairly significant international effort to push Saddam out of Kuwait, but Gulf War II was essentially just a US effort. Why? For Gulf War II nearly all other countries looked at Saddam and saw a thug in Iraq and concluded that he was just Iraq's problem. The old remark, maybe from Churchill, that "America always does the right thing after trying everything else" has some truth to it. We are too eager to squander our blood and treasure on absurd foreign adventures. And not just foreign: Now the NSA, FBI, DHS, and more are all going hysterical running around in circles, stirring up dust, and accomplishing next to nothing good and possibly doing a lot of harm. But as soon as someone rolls back the DHS, the other party will be out for blood at the next pressure cooker in a shopping mall. It's an old story: In medicine it was long, "The person is sick. We don't know why they are sick. We don't know what to do. But we must do something." which was often harmful. So, a few terrorists do this and that, take advantage of our old silly policy to give any airplane to any terrorist that asks, and we go all hysterical and start bankrupting ourselves and throwing away our Constitution. Solution: Have the voters wise up. Get that by better information from the Internet. A current case is Syria: We could sit here and debate for hours which is worse, Assad or some of, maybe the most powerful of, the rebels. What do we want there, Assad, in with Iran, wants to attack Israel, a thug in his home country, or some rebels that might lead to an Al Qaeda takeover, turn Syria into a base for radical Islam, attack Israel, etc.? It's ugly there; people are suffering and dying; the US should do something? My guess is, the US should do little or nothing. The enemy of my enemy is my friend? Well, not always!
