If ISIS succeeds in buying a Pakistani bomb and detonating it in the US then every life In ISIS controlled territory is forfeit.

The only question will be how many of the 200 million Pakistani lives will be forfeited as well. Using nukes could mean the end of Islam. Americans will not long linger over the morality of killing those who kill them. And no one should underestimate our nation's exceptional ability to slaughter billions if need be. Pakistanis should pray that ISIS is lying.
