Ditto. Sounded like a poorly camouflaged call for the UN to police the world, after everyone - everyone - was disarmed.
You're right. The producer of the film, Julian Blaustein thought that the US should surrender some of its sovereignty to the UN. He felt the US was being grossly unfair to the Soviet Union (Stalin was still in charge in 1951).
I'm not making this up. If you have the DVD, watch the extras.
