> Just read the Wikipedia article on the Gulf War. It's clear GH Bush pursued it to keep the oil price stable.
... Have you made any effort to try to learn foreign policy? Or are you relying only on piecemeal reading of events and your predisposed biases to determine your worldview?
Most politicians read a lot (Trump is an exception, and he's terrifying for it), and much of what they read is public policy theory books, things like Why Nations Fail or On the Origins of War and the Preservation of Peace. From these books, they tend to formulate their views on policy (including foreign policy) based on certain schools of thought, and you can often tell who influences these thoughts based on how they frame arguments and defenses.
The Gulf War was principally caused by Saddam Hussein reckoning he could invade Kuwait quickly enough that no one would care to try to stop him (this is what Russia more or less successfully did in Crimea). The other principal Arab states who did not like Iraq--notably Saudi Arabia and Egypt--were never particularly likely to accede to these demands. (Iraq did try to link Kuwait to the Israeli-Palestinian peace process, but that was more of a stalling tactic than an actual honest effort to further that peace process, although it did incidentally do so). When Iraq began making noises about invading Saudi Arabia, that's when the US launched Desert Shield and subsequently Desert Storm.
And yet, when you listen to the testimonies of the officials who planned the war, it's clear that they hewed to a definitive Clausewitzian view of war: the planning of war needs to be shaped around the political objectives it is meant to achieve. And the political objectives they gave as their design for war was to a) remove Iraq from Kuwait and b) prevent Iraq from being able to exert regional power for 20 years. Note that oil isn't a primary objective. Of course, the Middle East being what it was, any planning of major operations in there is going to take into account near- and long-term impact on oil supplies, and it's not exactly a secret that the State Department's general grand strategy for the Middle East is "keep the oil flowing." But that doesn't mean that the only goal is keeping oil--if it were, the US would not have invaded but instead pressured Saudi Arabia to just deal with the Iraqi annexation of Kuwait (note that oil didn't stop flowing until Iraq's withdrawal from Kuwait).
You also have to keep in mind that you can't stick your head in the sand, ignore the world, and expect to suffer no consequences. The current migrant crisis in Europe is entirely caused by European unwillingness to deal with the issue in Syria.
