Sadly, Pakistan lacks options. No allied nation trusts AAZ with a single dollar. Rightly so.
Pakistan has 2 basic problems concurrently.
1) WoT has caused both capital flight and drop in FDI. This is damaging the economy, dropping confidence etc.
2) High commodity prices have caused runaway inflation. Wiping out the lower middle class and causing a surge in poverty.
Pakistan needs to make a choice, stay in the WoT and get nothing in return except death, or leave the coalition-face sanctions-but hopefully gain stability.
It cant control 2, it can have some impact on 1. We are sanctioned often by the US, and although it would hurt, it may just shock start the leadership into taking responsible decisions. Sad truth is that until Afghanistan is stable, we will not be stable UNLESS we pull out and disassociate ourselves with the failed US policy.
