First of all how will Arab states establish an un-interrputed supply of oil given that India will launch a naval blockade of Pakistan?
Second, what good is oil going to do to Pakistan when we would need urgent re-supply of our military forces given the high attrition rate that Pakistan will suffer at the hands of numerical superior India.
Arabs can dispense with some of their fighter jets, tanks, gunships, artillery and anti-tank missiles and ifv, which will greatly boost the offensive potential of Pakistan.
One alternative scenario I could see is Arabs sending money to China which starts a major arms lift to Pakistan.
The question is are Arabs willing to help their fellow Muslim Brothers, the Pakistans over India? Or will Indian economic ties overrule any notion of muslim solidarity.
