 Kenney left day-to-day operations at SAC in the hands of his deputy commander, Major General St. Clair Streett.Part of the reason for Kenney's lack of focus on SAC was also his assignment as U.S. representative to the United Nations Military Staff Committee, which appeared at that time to be potentially an important assignment.In January 1947, Streett was replaced by Major General Clements McMullen.
