Incursions ?
The Falklands are no different than Cayman Islands, Tristan Da Cunha, Turks and Caicos, Pitcairn Islands, Diego Garcia and all the other bits and pieces left over from the British Empire many of which the US uses from time to time e.g. Diego Garcia and air bases in Cyprus.
France doesn't just occupy some of its old colonies it actually incorporates them into France itself e.g. French Guyana in South America. It also retained a couple of islands in the Gulf of St Lawrence off the coast of Newfoundland.( St Pierre et Miquelon)
The Caribean islands are self governed and autonomous from Britain. Though within the sphere of influence of the Americas, wars are not being fought over these interests. Diego Garcia, the Pitcairns, Cyprus air bases are not with this sphere. The Falklands are inhabited by 14 people, who’s, according to the article, destiny is now determined to be “non-negotiable”.
France has always, since the French Revolution, absorbed its world holdings as a part of France... its not autonomous.
Interesting you should mention the two French islands in the Gulf of St. Lawrence. After the French lost the French & Indian War they ceded all of their remaining terrrotory to the British. They were allowed to keep two small islands, so that, according to my college History prof, they would have some land to support their fisheries. French fisherman would catch cod and be able to land them on their islands so that the fish could be dried, salted, and packed for shipment back to France.
