There are several problems with this theory. First of all, the U.S. government never blamed any other country or group for the tragedy. Secondly, the object streaming away from the plane was its nose, which the computer model demonstrated. The CIA was involved in the investigation because, at that time, the FBI didn't have the computers to do sophisticated modeling. The official 341-page report by the National Transportation Safety Board says the fuel tank was most likely ignited by a short circuit, not a nefarious government missile.
