Asymmetric Warfare

I just saw a headline that quoted someone as saying "you've got nuclear bombs. we have suicide bombers."

Here's a poorly thought-out idea:

Is it possible that if Iran is allowed to have nuclear weapons, terrorism would stop?

Although on the other hand, as long as Afghanistan is politically, socially, and economically unstable, it seems unlikely for terrorism to stop so I don't know how much it really has to do with Iran.
