The U.S. military wants the "Iron Dome". Israel used the technology to knock 85% of the missiles Hamas fired at them from Gaza recently, out of the sky. Israel has agreed to give the United States the know-how needed to produce interceptors, but it is not interested in co-production yet. The United States has provided hundreds of millions of dollars to assist Israeli or joint U.S.-Israeli missile defense programs like David's Sling. Iron Dome was developed by Israel on its own.
