For God's sake man please stop making references to body organs. Iran nor KSA are kidneys of Pakistan, they are not even Pakistan's testicles. They are two regional countries that Pakistan has relations with it, that's it. Pakistan does not need them for survival, the population of Pakistan is larger than both those countries, the natural resources of Pakistan is also adequate enough to sustain Pakistan for anything else there are other countries that can supply Pakistan. You're talking as if they are vital organs, that is nonsense.
If Iran or KSA are Pakistan's kidneys then Pakistan badly needs a kidney transplant.
