President Donald Trump’s recent suggestion to revive nuclear testing has sparked alarm among Pacific island nations still grappling with the devastating legacy of nuclear tests conducted from the 1940s to the 1970s. The long-term repercussions of these tests have led to severe contamination, health issues, displacement of communities, and ongoing disputes over compensation and accountability.
In particular, the Marshall Islands—comprising 1,200 islands and atolls—continue to be haunted by the U.S. nuclear tests that resulted in the detonation of 67 bombs between 1946 and 1958. During the 80th United Nations General Assembly in September, Marshall Islands President Hilda Heine urged the UN to formally apologize for its role in permitting these tests, despite the local population’s opposition.
Heine emphasized the need for healing through acknowledgment, stating, “We can’t undo the past, but as a United Nations, we owe it to ourselves to make amends through the adoption of a resolution that formally apologizes for the failure to heed the petition of the Marshallese people.” This call to action highlights her belief that understanding and addressing historical injustices can pave the way toward restoring faith in international institutions.
As global tensions rise, President Heine expressed concern that past lessons from the Marshall Islands should serve as a catalyst for international efforts to mitigate nuclear threats. Trump’s alarming October 30 post on Truth Social raised uncertainties about potential resumption of explosive nuclear testing. He referenced the U.S. nuclear arsenal, noting, “The United States has more nuclear weapons than any other country” and hinted at a directive for the Department of War to commence testing.
Paul Aversa, a program assistant focused on Nuclear Disarmament and Pentagon Spending, called Trump’s plan a hazardous move backward. Aversa warned that any reversion to nuclear testing would not provide greater security and could exacerbate global tensions, especially as Russia has indicated it would respond proportionately to U.S. nuclear testing. This could provoke other nations to follow suit, raising the specter of a renewed arms race.
The legacy of nuclear tests in the Pacific is stark, with over 300 nuclear detonations conducted by the United States, the United Kingdom, and France in the region from 1946 to 1996. The consequences of these tests persist, manifesting in high rates of cancers, birth defects, and other health issues across Pacific communities. Key sites of testing include the Marshall Islands’ Bikini and Enewetak Atolls, France’s Moruroa and Fangataufa atolls, Christmas Island under British control, Hawaii’s Johnston Atoll, and multiple sites in Australia.
The Pacific islands continue to bear the burden of these historical actions, and as calls for recognition and resolution grow louder, there is hope for renewed international dialogue aimed at addressing the past and safeguarding the future.
