ISIS Buying Nuclear Weapons From Pakistan?

What do ISIS members and Pakistan citizens both have in common?

They are adherents of the Muslim Sunni faith.

And that is exactly where the potential for ISIS to acquire a nuclear weapon comes from.

Iran is a predominantly Shiite country which is an enemy of both ISIS and Pakistan. Now that there is a very realistic threat of Iran becoming a nuclear power it would be in the interest of Pakistan to arm ISIS with a nuclear weapon.

Since Pakistan would face retaliation from Iran for a direct nuclear attack, it would serve Pakistani interests to arm a proxy group, in this case the Islamic State in Iraq.

The question would be why would Pakistan arm a group with a nuclear weapon that could easily be traced back to it?

For starters, Islamabad could deny culpability by blaming it on corrupt officials with access to its missiles. And it might well count on the fact that Tehran could not retaliate without certain proof of the origin of the missile.

Another reason why this strategy might be of interest to Pakistan is because it would be able to launch a counter attack with a weapon that is deployed beyond its borders in the event that it experiences a preemptive attack from either India or Iran.
