Actually, the US doesn't get that much of it's oil from the Middle East (that mostly goes to Europe and Asia). We get much of our oil from Venezuela, Mexico and Nigeria, especially in the eastern half of the US. While Nigeria has it's Muslim/Christian/Pagan conflicts, that's mostly an internal struggle (for now). Theft and corruption is probably a bigger problem for keeping Nigerian oil flowing.
The way I see the charts, more than a quarter of our imported oil supply comes from Muslim controled contries in the Mideast and Africa. That's a lot of oil, means, and opportunity.
