After President Volodymyr Zelensky mused that only by joining NATO\u2014or by acquiring nuclear warheads\u2014could he freeze Russia\u2019s lightning war against Ukraine, a global expert on atomic arms conducted a fascinating thought experiment.<\/p>\n
Could the besieged democracy actually produce a nuclear bomb and the missiles capable of delivering that all-powerful explosive across Ukraine\u2019s border, able to reach the launch pads of Russia\u2019s blitz?<\/p>\n
If Ukraine succeeded with its own version of the Manhattan Project, could that advance freeze the Kremlin\u2019s campaign to take over the liberal enclave, without Kyiv ever having to detonate a single device?<\/p>\n
These are the interlinked puzzles that Alexander Bollfrass, an acclaimed scholar on nuclear weaponry at the London-based International Institute for Strategic Studies, set out to solve, first in a groundbreaking think piece<\/a>, and then in an interview with Forbes.<\/p>\n Dr. Bollfrass, head of strategy, technology and arms control at IISS, tells me in an interview that he war-gamed this scenario purely to predict the potential consequences of a hypothetical Ukrainian drive to craft an A-bomb, and whether a stockpiled weapon could become the ultimate guardian of a permanent ceasefire.<\/p>\n Yet Bollfrass, who as a postdoctoral fellow at Harvard designed war games for the university\u2019s Davis Center for Russian and Eurasian Studies, says he drew on Ukraine\u2019s real-life access to plutonium and uranium, and its current missile expertise, to construct these simulated war and peace maneuvers.<\/p>\n Ukraine’s Chernobyl nuclear power plant, site of the world’s worst nuclear accident, was recently … More targeted by a Russian drone.
