Iran has secretly designed Nuclear Warhead so advanced that it is still being kept largely a secret in the U.S. and Britain.
What details have been released is that it uses a "two point implosion" and that they have tested components of this design.
This is the first claim that Iran has sought such advanced weaponry, which nuclear experts have called "breathtaking."
The IAEA has sent a dossier to Iran, asking for explanation on this and some other findings that are not known at this time.
