United States Dilemma

   The U.S.accuses Iran of supplying bombs, known as "explosively formed  perpetrators" (EFPs) to Iraqi forces, who oppose the U.S presence in the country.
 This is obviously bad considering Iran is an enemy of the U.S.  Story here

QUESTION: how do we stop them?

The U.S. Defense Department routinely sells its surplus "parts" to other countries. Currently it was selling parts from its retired F14 fleet, parts that are coveted by Iran.   Story here
QUESTION: how do we stop them?

The Associated Press had found weaknesses in the U.S. surplus-sale security that allowed buyers for countries including Iran and China to obtain  sensitive surplus, including aircraft parts and missile components.  The Government Accountability Office,  has conducted its own inquiry into surplus security and found loopholes.
& have found valuable surplus accidentally getting included in boxes of what are supposed to be nuts-and-bolts-type hardware.
Some of those spares from the newly retired fleet likely have already been sold, Jack Hooper, a Defense Logistics Agency spokesman, said
In at least one case, surplus gear made it to Iran, investigators say. A Pakistani arms broker bought Chinook helicopter engine parts for Iran from a U.S. company that had bought them in a Pentagon surplus sale, and the parts got to Iran, according to Immigration and Customs Enforcement agents.    This is obviously bad considering Iran is an enemy of the U.S. But it is also quite unforgivably STUPID.  I mean what kind of idiot arms his own enemies?  Oh yeah, the U.S.  Why?  easy, our friends and enemies list rotates every few
 years so we are never quite sure who is who.

Friends and enemies list. notice how they re both the same, only the years are different

• Iran a former ally / current enemy; 
• China former enemy / current ally(?) tenuous at best as are many of our allies.  Most of our allies are only as strong as the last millions in money we sent them them
  
• Iraq former ally, when Iran was enemy
• Russia, former enemy, current ally(?) would you trust them?
• Bin laden friend when he fought against Russia
• Saddam Hussein, friend when he fought Iran who was enemy of U.S. at the time
• Noriega friend  til he wasn't.......
• Castro enemy BUT
• Batista, Cuba's dictator prior to Castro was a friend????

a dizzying array of on again off again friends / foes.  
Stopping Arms Sales to Enemies(?) Or are they friends???   Guess it depends on what day of the week it is.
