Moscow has proposed voluntarily keeping its limits for just one more year, a departure from the previous five-year extension. While Russia is still awaiting a formal reply, U.S. President Donald Trump ordered the resumption of nuclear testing in response to alleged covert tests by Russia, China, and Pakistan, a claim that immediately went critical, triggering a chain reaction of similar statements worldwide, with Moscow and Beijing in particular warning of reciprocal action.

Even a limited nuclear exchange, a 2022 study in Nature Food (Xia et al.) shows, involving just 100 Hiroshimasized weapons would drop global temperatures by about 5℃, cause agricultural yields to plummet by 1040 per cent, trigger a severe nuclear winter, and leave about 5.3 billion starved people within two years. Trump himself has admitted the existing stockpile can "blow up the world 150 times." After the first round, who will bother with the other 149? Kathryn Bigelow's movie A House of Dynamite captures the agony of time-pressured nuclear decision-making, whether to retaliate and risk annihilation or hold fire and lose Chicago.
