The groundbreaking nuclear deal President Obama has been forging with Iran will reportedly bar them from developing a nuclear weapon. But since people often call nuclear weapons "nucular" weapons, Iran has figured out that they can easily use this distinction without a difference to continue with their atomic weapons development, and when they are discovered in the act, or actually succeed in developing a bomb, and they are confronted about their activities, they can say they are not working on nuclear weapons, but rather, "nucular" weapons, and those were not covered in the agreement. And then they can say, when asked if their program is indeed producing nucular weapons, they can say: "It depends on what the meaning of the word 'is' is."
And once we hammer out a new deal to ban Iran from developing "nucular" weapons, they will alter their program again to produce "atomic" weapons.
(Lots of people, including former President George W. Bush, incorrectly call nuclear weapons "nucular" weapons; and since treaties are based on the letter of the law, Iran could try it, and they might even get away with it. So I hope the Iran deal includes word derivations and all terms referring to nuclear weapons to avoid the possibility of Iran using this tactic.)
