Turns out France isn't so innocent. France is hanging on to these territories like grim death because it wants a presence in the Pacific (and elsewhere). All 'global power' nations want to spread out over the globe. Mayotte has a poverty rate of 77%, the highest of France's territories:
France is a global power, with territories in Western Europe, North and South Americas, the Caribbean, and the Indian, Pacific, and Antarctic Oceans. The presence of territories in so many different regions is an essential geostrategic asset for France. For instance, it is what allows France to own the second largest Exclusive Economic Zone (EEZ) on Earth, behind the United States. Indeed, as much as 96% of the French EEZ is due to these overseas territories.
However, France may lose part of these territories if the French government is not careful and maintains its seeming complacency. In metropolitan France, overseas territories seem too often to be a mere afterthought. Metropolitan citizens rarely, if ever, hear about them on the news, and French politicians seldom mention them in public statements. A disconnect between metropolitan and overseas France, along with poor to very poor socio-economic environments represent a critical danger to France’s global integrity.
Military and Geopolitical Assets
The French overseas territories allow France to use its military power globally, complementing military bases in foreign countries and her aircraft carrier. As a matter of fact, France is the third country in the world enjoying the biggest global military footprint, behind the United States and Russia (Tenenbaum, Paglia, Ruffié, 2020, p. 33). These overseas territories “give France secure platforms for power projection all over the world, and the possibility to redeploy military assets in response to changes in the strategic situation.” They allow France to be present “as a credible partner and ally in both the Indian Ocean and the Asia-Pacific region.” (§272) They enable France to rapidly intervene outside its metropolitan territory and contribute to regional military cooperation (p. 2).French overseas territories also grant obvious economic and maritime benefits to France. Most notably, they give France the world’s second largest EEZ. Especially in the Indian and Pacific Oceans, this EEZ holds the potential of containing reserves of hydrocarbons and strategic minerals which could be necessary to France’s strategic autonomy (Tenenbaum, Paglia, Ruffié, 2020, pp. 76-77; Cyrille P. Coutansais, “L’empire maritime français : Enjeux et défis,” Les Grands Dossiers de Diplomatie no. 44 (April-May 2018), p. 37). Such reserves are, as of yet, either unexploited or unexplored, but may very well contain precious resources. Additionally, the French EEZ contains biodiversity which may prove useful in terms of food, medicine, and cosmetics (Coutansais, 2018, pp. 37-38).
