Wouldn't work, the British would coin a Bazillion $ coin and buy it back.
Well then Argentina should mint a diamond-chipped quadrabazillion $ coin!
It cost about Great Britian $500k per Falklander to attack and free them 30 years ago. May not continue to be worth it. The U.S. should have stayed out of it and let the British bomb the mainland where everyone could learn of the consequences. In the US we used to hang cattle rustlers-not because of the lost cattle. It was because of the difficulty in keeping them from being stolen. Up the ante.
