The death of Dubs was listed as a "Significant Terrorist Incident" by the State Department. Documents released from the Soviet KGB archives by Vasily Mitrokhin in the 1990s showed that the Afghan government clearly authorized the assault despite forceful demands for peaceful negotiations by the U.S., and that KGB adviser Sergei Batrukhin may have recommended the assault, as well as the execution of a kidnapper before U.S. experts could interrogate him. The Mitrokhin archives also indicate that the fourth kidnapper escaped and the body of a freshly killed prisoner served as a substitute for the U.S. inspection. Other questions remain unanswered.
