As someone pointed out to me earlier this week here on HN, Seymour Hersh's article on the Bin Ladin assassination, the real story of Al Qe'da is that the Saudis funded it tacitly. And as a result Saudi government is partially responsible for 9/11.

The sooner we figure out how to make petroleum irrelevant, the sooner places like Saudi lose their influence. Gas == War.
