"How crucial Balochistan is to Washington can be assessed by the study "Baloch Nationalism and the Politics of Energy Resources: the Changing Context of Separatism in Pakistan" by Robert Wirsing of the US Army think-tank Strategic Studies Institute. Predictably, it all revolves around Pipelineistan.
China - which built Gwadar and needs gas from Iran - must be sidelined by all means necessary. The added paranoid Pentagon component is that China could turn Gwadar into a naval base and thus "threaten" the Arabian Sea and the Indian Ocean.
The only acceptable scenario for the Pentagon would be for the US to take over Gwadar. Once again, that would be a prime confluence of Pipelineistan and the US empire of bases.
Not only in terms of blocking the IPI pipeline and using Gwadar for TAPI, control of Gwadar would open the mouth-watering opportunity of a long land route across Balochistan into Helmand, Nimruz, Kandahar or, better yet, all of these three provinces in southwest Afghanistan. From a Pentagon/NATO perspective, after the "loss" of the Khyber Pass, that would be the ideal supply route for Western troops in the perennial, now rebranded, GWOT ("global war on terror").
During the Asif Ali Zardari administration in Islamabad the BLA, though still a fringe group with a political wing and a military wing, has been regrouping and rearming, while the current chief minister of Balochistan, Nawab Raisani, is suspected of being a CIA asset (there's no conclusive proof). There's fear in Islamabad that the government has taken its eye off the Balochistan ball - and that the BLA may be effectively used by the US for balkanization purposes. But Islamabad still seems not to have listened to the key Baloch grievance: we want to profit from our natural wealth, and we want autonomy.
