Pakistan doesn't play any 'Iran' card, nor does it extract money from the Gulf royals in order to do so. There was new a few months back of terms being extended on a loan from the UAE, yes you have to pay them back, like with the World Bank loan. The UAE now has strategic ties with India, and the Saudis give Modi a red carpet welcome. The wind has been sailing in that direction for quite a while now.
Pakistan/Iran trade will gain more ground.
I noted that you linked boundaries to threats and disputes. Well Pakistan and Iran have NEVER had any dispute, despite sharing a 596 mile border, which was also one of the most open, what does that tell you?
Also I'd ask you to stick to the topic, hard I know seeing as you are Indian American.
You say there is no enmity between Pakistan and Iran. You say that you are not getting payoffs from Saudis and Gulf Arabs. The financial dealings speak for themselves. The amount of economic trade between Pakistan and Iran speaks for itself
Saudi gave Modi a red carpet welcome because they want India to be a buyer of petroleum who can pay them cold hard cash. India allowed them finally to invest in an oil refinery
If India cuts Iran a similar deal they will be singing Modi's praises.
