Such a deal would be a violation of a 2007 United Nations Security Council resolution that forbids Iran from transferring, selling, or supplying arms or related material. according to http://www.haaretz.com/news/diplomacy-defense/iran-supplied-syria-with-radar-system-to-thwart-surprise-israel-attack-1.299350
This might be a non-event.
“The mid-2009 transfer was described in recent months by two Israeli officials, two U.S. officials and a Western intelligence source, and confirmed Wednesday by the Israeli military.”
Doesn’t sound like a non-event.
