Technologically, our adversaries have the capability to blind imagery satellites or jam satellite signals. According to Leonard David's article in Space.com, laser technology is rapidly becoming available to blind imagery satellites. Countries and individuals have also shown they are willing and able to deliberately disrupt communication satellites. In 1997, India jammed Tongasat because of a disagreement over possession of a geosynchronous orbit slot. In 1998, MED-TV accused Turkey of jamming its Kurdish broadcast channel that is beamed to 70 countries. In early 2003, the FBI charged six people for selling software and decryption devices that allowed consumers to 'steal' satellite television signals (e.g., DirectTV) which they had not paid for. As late as the summer of 2003, the Iranian Embassy in Cuba reportedly jammed Voice of America satellite broadcasts being sent to Iran.
