A new Polish film has prompted debate in Poland over whether a colonel who defected to the United States during the 1970s deserves to be honored by his home country.

For over nine years, Ryszard Kukliński provided the CIA with more than 40,000 pages of documents regarding the innermost secrets of the Warsaw Pact, including war plans and intelligence that was deemed of "truly great strategic significance" by Zbigniew Brzezinski, President Carter's national security adviser.
