Not unless you're completely divorced from reality.
Again, I cannot believe the number of times this bizarre argument comes up: "Why shouldn't the psychotic totalitarian ruler of some despotic country have nuclear weapons when nations like the U.S. and Britain do?"
This is like asking what difference there is between a policeman having a gun and a serial killer having a gun. It's all about the gun, right? What do objective standards of behavior have to do with it?
The Iranians have as much as declared that they would love to launch an atomic attack on Israel. Maybe you're one of those people who don't care, as long as it isn't an attack on the U.S. That's your privilege, I suppose. You can always hope the Iranians don't slip their favorite terrorists a warhead or two.
