Among the two most alarming revelations is the already completed sale and delivery, to Venezuela by Russia, of nearly 2,000 advanced, shoulder-fired anti-aircraft missiles capable of hitting aircraft as high as 19,000 feet. Equally and perhaps more alarming is an October agreement between Iran and Venezuela. The agreement establishes a joint ground-to-ground missile base on Venezuelan soil and calls for the sharing of missile technology and the training of technicians and officers. In addition, Venezuela may use the missiles as it chooses for “national needs” and in case of “emergency.” Several types of missiles will be deployed, giving Venezuela the ability to strike targets throughout South and Central America and throughout the U.S.
