Tom Armbuster writes in the Bulletin of Atomic Scientists about a little-noticed feature of Project 2025, the agenda for a second Trump administration prepared by the Heritage Foundation. The 900-page document calls for a resumption of nuclear testing. Armbruster is deeply knowledgeable about the horrible after-effects of atomic testing, whether in the open air or underwater.

Armbruster was US Ambassador to the Republic of the Marshall Islands, where several nuclear tests were conducted, which poisoned people, the land and the sea.

He writes:

There are few places more peaceful than a Pacific island. At 6:45 am on a March morning in 1954, that peace was shattered by the largest nuclear test in American history: Operation Bravo.

The Bravo test was a thousand times more powerful than the Hiroshima bomb. Now, 70 years later, Project 2025 is proposing a resumption of testing. That should alarm every military service member, downwinder, Pacific Islander, and taxpayer.

As US Ambassador to the Republic of the Marshall Islands, I joined in the solemn observance of “Remembrance Day,” the Marshallese national holiday that pays tribute every March 1 to those who lost their homeland, fell victim to cancer, or were otherwise affected by the Bravo shockwave and fallout.

The shorthand for the 67 nuclear tests from 1946 to 1958, including two undersea tests that wiped out rich Pacific marine life, is the “Nuclear Legacy.” It would be more accurate to call it the “Nuclear Wound.” The tests on Bikini, Enewetak, and Kwajalein wounded the land and the ocean, the people—both Marshallese and American servicemen—and the relationship between our two countries. Healing is marked in decades, if not centuries.

We’ve had the nuclear tiger by the tail for a long time. No leader of any country would want their legacy to be the use of such indiscriminate and destructive weapons. When I joined the Foreign Service from Hawaii, Ronald Reagan was President. A chance for nuclear disarmament came and went with his summit with Soviet leader Mikhail Gorbachev in Reykjavik. Today, the Soviet Union is gone but nuclear weapons are still here. We’ve made progress, but Reagan’s vision of a nuclear-free world remains out of reach. Until we achieve that goal, maintaining a test ban is in everyone’s interest. It is part of the legacy we leave our children.

It is simply incomprehensible that the people who created Project 2025 would advocate a return to one of the most destructive practices in our history.
