https://www.theguardian.com/uk-news/2016/jan/24/jeremy-corbyn-power-sharing-deal-falkland-islands-argentina reports, "Jeremy Corbyn has told Argentinian diplomats he wants a Northern Ireland-style power-sharing deal for the Falkland Islands"
Why do this statements lack foresight? Because:
1. In a referendum (2013), over 90% of all Falkanders wanted UK to remain to have sovereignty over the Falkland Islands.
2. Letting another country having joint sovereignty over a British Overseas Territory creates a precedent for joint-sovereignty for all 14 British Overseas Territories (which include Gibraltar).
3. Such statement is likely to further inflame UK-Argentinian stance on the Falklands.
4. Demeaning the sacrifice British Armed Forces who bravely fought the Falklands War in the early 1980s.
5. Jeopardising British interests at home and abroad.
