"The U.S. government asserts that it can still hold the copyright to those works in other countries."
Going a little further I read : "the U.S. Government may obtain protection in other countries depending on the treatment of government works by the national copyright law of the particular country." (from the CENDI FAQ), which is adequate with private international law.
Any link to information about that would be very welcome too.
