Personally I think Pakistan, under Musharraf has become more of an ally than in the past and is, imo, the biggest ally in the War on Terror. Before the United States winning a sweeping victory in Afghanistan NO foreign power had been able to conquer or occupy Afghanistan for over 800 years. Pakistani logistics and military support to keep militants from regrouping and crossing the boarder like they let them do against the Soviets ensured a much quicker victory.
