Iran because their leadership supports Islamic sects that are violent, and cannot monitor the stockpiles of uranium and nuclear technology that they currently maintain.

I trust our safeguards and nuclear protection than a Islamic Republic that has a stated goal of destroying Israel.

If we give everyone a rifle, it's more likely someone will get shot.
