1. You assume that the pipeline will eventually get built, which is unlikely for several decades considering the financial mess that Pakistan and Iran are in. Remember Chinese and even a Pakistani bank withdrew funding promises fearing US sanctions.as per I have read, Gas Price is around $2.5 per MMBTU in North America, while its close to $10 per MMBTU in Asia. and it all shuccck..
but by any criterion, $6-$7.5 per MMBTU is a pretty good price in Asia, in fact, which we hope for IP gas pipeline :thumb:. and dont forget, if US imposes ban on Pakistan, if, then they will themselves get banned from using Pakistan's space/resources for their war purposes, , which has cost over $200bn loss to Pakistan since 2002. the Afghan War, which converted Pakistan also into a War Affected countries, causing heavy losses since then, destroying any type of industrial developments which could take place in Pakistan during last 10 years.....
in sum, i think Pakistan would only get benefit by making distance from US/West, whether its Pakistan kicks them or they themselves kick Pakistan :thumb:
2. As the US is pulling out of Afghanistan in 2014, they will not need Pakistani airspace and do not stand to lose much. On the other hand Pakistani stands to lose heavily because it will no longer get the huge transit fees it was getting for allowing US and Nato supplies overland from Karachi. And no to mention the billions that the US will stop paying to Pakistani Army. (It is unlikely that the Army will allow the civilian government to do anything that will jeopardize this fountain head of funding.)
3. You seem to assume that Pakistan became affected because of US presence in Afghanistan. It is not true. In fact Pakistan was even more actively involved in the Afghan insurgency against the Soviets.
You can see the situation is not as simple as it appears.
