The only problem is we still need their damn oil. Please, Elon Musk, save us from dependence on these assholes' oil. The sooner we can find a replacement for middle eastern oil and/or their oil runs out, the better.
Just to give some numbers, here is where we (the U.S.) got our oil in 2013:
U.S.: 2,720 million barrels
Canada: 1,147 million barrels
Saudi Arabia: 485 million barrels (OPEC)
Mexico: 335 million barrels
Venezuela: 294 million barrels (OPEC)
Russia: 168 million barrels
Columbia: 142 million barrels
Iraq: 124 million barrels (OPEC)
Kuwait: 119 million barrels (OPEC)
Nigeria: 103 million barrels (OPEC)
Ecuador: 86 million barrels (OPEC)
Angola: 79 million barrels (OPEC)
Brazil: 55 million barrels
U.K.: 54 million barrels
Other OPEC: 67 million barrels
Other non-OPEC: 338 million barrels
Ignoring the type of oil (pretty sure we're exporting natural gas like a fiend right now due to fracking), we need to cut 21% to get away from OPEC altogether, or 12% just to get away from the Middle East. In the U.S., 47% of oil goes to gasoline, 20% to diesel and other fuel oil, 13% to liquefied petroleum gases like propane and such, and 8% for jet fuel. All this info is from eia.gov, by the way.
So it while it is still an enormous problem, it's not insurmountable. In fact, it's inevitable. We won't go cold turkey, but we will almost certainly keep chipping away at that deficit with continued efficiency improvements on cars and other vehicles, growing emphasis placed on fuel efficiency, and continued improvements in domestic oil production and refining. Ideally the cleaner improvements will come fast enough that we don't have to rely on the latter, but it'll happen sooner or later.
