ICBMs can't be GPS jammed -- they don't have guidance systems.
Sure they do, but they don't rely on external signals like GPS. They use accelerometers, gyros and stuff like that. Some may have used star trackers and/or "horizon sensors" which theoretically are "external signals" but not anything like GPS.
