nuclear weapons

Research affiliate Thomas Neff, a physicist known for his proposal aimed at “reducing the global stockpile of nuclear weapons and helping stabilize the former Soviet Union,” has died at age 80, reports Harrison Smith for the Washington Post. Credited with the “Megatons to Megawatts” agreement, “Dr. Neff spent years working in arms control, nuclear weapons proliferation and uranium markets, bridging the divide between experts who specialized in the kind of highly enriched uranium used for warheads and the far less enriched version used for electricity generation,” Smith writes.

Research affiliate Thomas Neff, a physicist whose work with nuclear weapon conversion led to an agreement “that reduced nuclear threats and produced one of the greatest peace dividends of all time,” has died at the age of 80, reports William J. Broad for The New York Times. Neff’s idea of converting Soviet nuclear weapons into electricity used to power American cities “turned some 20,000 Russian nuclear arms into electricity, lighting billions of American lightbulbs.” 

Writing for The New York Times, Steven Simon, a fellow at the MIT Center for International Studies, and Jonathan Stevenson of the International Institute for Strategic Studies explore the Biden administration’s response to Russia’s nuclear threats. “The United States and NATO should be less deferential to Mr. Putin’s attempt to wield the threat of nuclear weapons,” they write, “not only for the sake of supporting Ukraine but also to ensure global geopolitical stability in the future.”

A series of recently tested hypersonic missiles in North Korea brings forth concerns about vulnerability for U.S. troops and their allies in Asia, reports Josh Smith for Reuters. Research affiliate David Wright warns that “South Korea and the roughly 28,500 U.S. troops based there are so close that incoming missiles could fly on even lower trajectories, with a much shorter flight time, making defense more difficult,” writes Smith.

MIT Prof. M. Taylor Fravel and University of Pennsylvania Prof. Fiona Cunningham explores what China’s investment in its nuclear arsenal means for U.S. – China relations in a piece for The Washington Post. “Two shifts in China’s nuclear thinking may be happening. First, Chinese leaders believe that they now need to threaten the United States with greater nuclear damage to deter a U.S. nuclear first-strike: a handful of warheads is no longer enough,” they write. “Second, China’s leaders may be finding Beijing’s promises not to engage in a nuclear arms race increasingly difficult to fulfill — or less of a priority than deterring U.S. nuclear use with more confidence.”

Prof. Vipin Narang writes for Foreign Affairs about the state of North Korea’s nuclear program following President Trump’s summit with North Korean leader Kim Jong Un. Narang argues that the U.S. should try to “establish a stable deterrence regime rather than pressing for immediate unilateral disarmament, ensuring that nuclear dangers on the Korean Peninsula are managed responsibly.”

Professor Noam Chomsky reflects in The Huffington Post on the anniversary of the dropping of the atomic bomb on Hiroshima and the age of nuclear weapons. Chomsky argues that, considering their tremendous capacity for destruction, it is only by luck that we have survived with nuclear weapons for so long.

Professor Jim Walsh speaks with Jeremy Hobson of NPR’s Here & Now about concerns that North Korea may be planning to conduct another nuclear test during President Obama’s visit to Japan. Walsh also speaks about current international issues on a larger scale, touching on both Syria and Ukraine.
