A major intelligence leader has told Congress that Iran has all the items it needs to build a nuclear weapon.

James Clapper, the Director of National Intelligence, sent a report to the Senate Intelligence Committee that states Iran has made enough significant advances in its nuclear program that if they chose to turn their back on world agreements and produce a nuclear weapon they could obtain it.

However, Clapper says that it would be very unlikely they would able to finish production of the weapon without other world powers discovering their work.

“We assess that Iran would not be able to divert safeguarded material and produce enough WGU (short for Weapons Grade Uranium) for a weapon before such activity would be discovered,” Clapper wrote. “The…central issue is its political will to do so.”

Clapper noted that Iran already has the largest stockpile of ballistic missiles in the Middle East and they are “inherently capable of delivering WMD (Weapons of Mass Destruction).”
