I agree that price rationing alone may not solve the issue and to think like that would be utterly foolish (reality doesn't follow an economic model, esp. such a broken one).

As for US/gasoline tax/war option, how about UK? They have high gasoline tax as the rest of the EU, but they are still with US in the oil wars.... err... I mean the great generational just war against terrorism (sic)

Well, i don“t know why UK is in the war. But i know that Sweden has a military force in northern Afghanistan supposedly for idealistic reasons helping the people of Afghanistan, when they and some other countrys in reality are lured by the US to be a part of the oil war.

EDIT: I hope Sweden as payment will get a share of the oil US is going to steal from the region.
