To all the Israel baiters, to let you know that they have nuclear capable SLBM's ready at any given moment. They have the complete nuclear triad in place. Nuking Israel is not an option.
Anyway, back to topic. Pakistan's greatest enemy:
Social enemy: corruption
Internal enemy: Balochi rebels
External enemy: Israel/India (although peace process with India and diplomatic contacts with Israel)
Long term rival: Iran
I'm surprised no one tookt he name of Iran as yet. We all know the muslim brother hood is non existant. Iran is a wannabe nuclear power. Iran is developing a port with Russia/India which is a rival port of Gwadar. Iran & Pakistan are fighting for more influence over Afghanistan for the past 40 years.
International community is pushing peace with India and Pak, but international community won't care about Iran-Pakistan. Both countries are same sized and have similar interests in the region and the world. Both want to be the Number One muslim power. Both want to benefit out of Central Asia trade. Both has historical differences.
