Get real? Take your own advice. If you don't think we would come up with a new "composite material" in a situation in which we no longer had viable access to "crude" than you're deluded. In fact, if you don't think we already have plans in place for such situations, then you're entirely disconnected from reality.
I'm not going to sit here and argue about hypothetical situations you've pulled out of your ass; you're neither intelligent or interesting enough. President
Obama did not create the hostilities in the Middle-East, and it's not his job to magically fix them. If that responsibility lies with anyone, it's with the nations that can't seem to handle their own shit. It is his job to protect our national interests and allies, and you are not privy to the information required to judge him.
You've got your head in the clouds. The world isn't ever going to be the place you expect it to be, so you've only got yourself to thank for your bitter disappointment.
