Pakistan has never helped Iran. They are more loyal to Israel, Saudia and US than Palestinian and Iran, therefore they will do nothing if they don't help Israel!
They are enough busy in playing with their neighbour India. They will do nothing. They have not even completel gas project to buy disscounted gas from thier neighbour Iran and help our economy a bit, let alone helping Iran! But Pakistani people are not the same with Pakistanis heads.
Iran has brave enough that has said it will destroy Israel whenever it can and it is 'IRAN' that has stood against Israel in the ME and the Israel whenever here Iran and resistance axis names wet it's pants! I don't think Israelis dare to attack Iran because it will be end of their occupation.
In any case even Pakistanis do not complete gas pipeline let alone helping us! Pakistan only follow it's benefits by following US and Saudis and not Islamic benefits.
