It wasn't until I reported my print piece on how much Barack Obama's foreign policy--from closing Gitmo to Iran to the global economy-- depends on the Saudis that I appreciated the influence Riyadh has over its Sunni ally Pakistan. One illustration of that: Pervez Musharraf, the former Pakistani military dictator pushed from office last year, flew on a Saudi jet to Riyadh this week to meet with Saudi King Abdullah, in what regional news outlets are suggesting could be part of a Saudi-brokered deal to spare Musharraf, now residing in London, from treason charges back home. (Musharraf is accused of illegally detaining judges during the country's 2007 constitutional crisis.) Those charges can apparently bring the death penalty.
