Pak relation with Iran is OK, while relation with Saudis are good.One thing I am curious about is the relations between Pak, Iran and Saudi. The three most powerful Muslim countries. How do they triangulate?
But it's the Iran-Saudi duo that is troublesome. As long as these two keep squabbling at each other, Saudis,by extension it also means other ME countries, will keep buying Western arms which enables west. Only reason usd is still alive is because of it is used for energy trade.
I am not sure pak brings anything to BRICS, just like India, at least not on economical front.
