After the war, Ritter resigned from active duty and returned to the Soviet
Union to look into a job with an American firm and to look up Khatiashvili.
After they got married in 1991, the FBI launched an investigation into
whether Ritter represented a risk to national security. Marrying a foreign
national would ultimately cost Ritter his high-level security clearance when
he became a U.N. weapons inspector and had to, as he put it, "interact with
the intelligence community."
