Iran already has nuclear weapons and has had them for years. While they did not make their own nuclear bomb, Iran possesses small tactical nukes made in America! And most likely has several of the suit case nukes made in the former Soviet Union.
What is interesting is how Iran got the bomb.
Iran acquired nukes from the United States the same way North Korea got its nukes! They bought our W-57 series tactical nuke from Israel!
President George Herbert Bush illegally transferred these baby nukes from our arsenal to Israel who in turn marketed and sold them to other nations.
Remember when North Korea first tested their first nuke? It was an utter failure. Why? Because they were sold the original smaller W-57 series that had a short shelf life. It was discovered later than when the mass of the nuclear material was increased approximately 20% the warheads became more stable, their shelf life and usability increased and those old weapons made in the 1950’s will still detonate–as we learned by experience on September 11.
