1. The Falklands had a referendum on whether to remain british or become Argentinan. 2 (I think that was the figure) Argentinian immigrants voted Argie. The rest of the island voted Brit. That should be the end of it.

2. Hong Kong. We rented HK from China. When the lease ran out there were 2 possibilities. A) a new lease agreement or the Chinese took HK back. They chose to do the latter.
