Career
After the Nazi defeat in 1945, he became the chief of one stay-behind network in West Germany, code-named KIBITZ-15. The British and United States intelligence services had set up clandestine anti-communist organisations supposed to "stay-behind" in case of a Soviet invasion. Walter Kopp was described by his own North-American handlers as an "unreconstructed Nazi," and the KIBITZ-15 network as "a group with Nazi tendencies" in Central Intelligence Agency documents released in June 2006.
In May 1950 Kopp wrote a letter to High Commissioner McCloy stating that he and a group of his friends were concerned over what might happen in case of a Russian invasion of Germany and wished to place themselves at the disposal of the Americans.
The offer must have appealed to the Central Intelligence Agency since Walter Kopp was made chief agent of the KIBITZ stay-behind network. In May 1953 Kopp"s contract with the Central Intelligence Agency was terminated "on the friendliest terms".
