You are right. We are so tied up in Saudi oil we have to look the other way on their terrorist activities. Until we start to tap our own reserves and become energy independent its going to be a gigantic ongoing problem.
Using our own energy supplies will not improve the situation with the Muslims in the Middle East oil producing countries. Even if we were not dependent on their oil, our allies would still be.
Our current situation with the Middle East oil producing countries isn't much different than what existed with Axis powers leading up to WWII. Just like the Axis powers, the Middle East oil producing countries are a threat to the whole world. The difference is, especially with Europe, the Allies are accommodating the invasion through liberalized immigration policies. It looks like, this time, the Allies will be conquered.
