New Caledonia, French Polynesia, and Wallis and Futuna are part of a worldwide chain of French colonies also including Kerguelen, Guiana, Martinique, Guadeloupe, Mayotte, Reunion, and St. Pierre and Miquelon, under the DOM-TOM (Ministry of Overseas Departments and Territories). It costs France billions of Euros a year to maintain this system, a clear indicator that it's something totally different from colonial empires of the past, which were based on economic exploitation, not subsidies. For more than 40 years France has been willing to spend vast sums to perpetuate its status as a medium-sized world power.
These conditions contradict what has happened elsewhere in the South Pacific. During the 1960s and 1970s, as Britain, Australia, and New Zealand voluntarily withdrew from their Pacific colonies, French pretensions to global status grew stronger. This digging in created the anachronism of a few highly visible bastions of white colonialism in the midst of a sea of English-speaking self-governing nations. When French officials summarily rejected all protests against their nuclear testing and suppression of independence movements, most Pacific islanders were outraged.
The final round of nuclear testing in the Tuamotu Islands in 1995 was a watershed as French national prestige had seldom sunk as low, both in the Pacific and around the world. Since that debacle, France has tried to mend fences by supplying economic aid to the independent states and granting enhanced autonomy to its colonies. As France becomes fully integrated into the new Europe, it's possible that the ability and desire to maintain remote colonies will decline, and the decolonization process will finally be concluded.
No other area on earth was more directly affected by the nuclear arms race than the Pacific. From August 6, 1945, until January 27, 1996, scarcely a year passed without one nuclear power or another testing their weapons of mass destruction here. The U.S., Britain, and France exploded more than 250 nuclear bombs at Bikini, Enewetak, Christmas Island, Moruroa, and Fangataufa, an average of more than six a year for more than 40 years, more than half of them by France. The U.S. and British testing was only halted by the 1963 Partial Nuclear Test Ban Treaty with the Soviets, while the French tests continued until unprecedented worldwide protests made it clear that the Cold War really was over (as usual, France was a slow learner).
The British and American test sites in Micronesia are now part of independent countries, but the Marshallese still suffer radiation sickness from U.S. testing in the 1940s and 1950s (some of it deliberately inflicted—the islanders were used as human guinea pigs), and the French are still covering up the consequences of their tests in French Polynesia. The end result of nuclear testing in Micronesia and Polynesia is ticking away in the genes of thousands of servicemen and residents present in those areas during the tests, and at the fragile underground Tuamotu test site used by the French.
The fact that the nuclear age began in their backyard at Hiroshima and Nagasaki has not been lost on the islanders. They have always seen few benefits coming from nuclear power, only deadly dangers. On August 6, 1985, eight member states of the South Pacific Forum signed the South Pacific Nuclear-Free Zone Treaty, also known as the Treaty of Rarotonga, which bans nuclear testing, land-based nuclear weapon storage, and nuclear waste dumping on their territories. Each country may decide for itself if nuclear-armed warships and aircraft are to be allowed entry. Of the five nuclear powers, China and the USSR promptly signed the treaty, while the United States, France, and Britain only signed in March 1996 when it became obvious they could no longer use the region as a nuclear playground.
