UN Sanctions allow rockets to be sent to Iran...

I guess there are some loopholes...

A draft U.N. resolution that would impose sanctions on Iran, including limits on global arms transfers, will not block the controversial transfer of Russian S-300 missiles to the Iranian military, according to U.S. and Russian officials.

The Obama administration had opposed the S-300 sale because the system is highly effective against aircraft and some missiles. The CIA has said the S-300 missiles, which have been contracted by Tehran but not delivered, will be used to defend Iranian nuclear facilities.

A key provision in the resolution made public this week states that all U.N. member states will agree to block sales or transfers of weapons. It lists tanks, armored vehicles, artillery, combat aircraft, warships and "missiles or missile systems as defined for the purpose of the United Nations Register of Conventional Arms."

A close reading of the missile section of the register defines those included in the ban as missiles and launchers for guided rockets, and ballistic and cruise missiles, and missile-equipped remotely piloted vehicles. However, the register states that the missile system category "does not include ground-to-air missiles," such as anti-aircraft missiles and anti-missile interceptors like the S-300.
