The New START treaty between the US and Russia, which limits each country to 1,550 deployed strategic nuclear warheads, is set to expire on Thursday, raising concerns about a potential new arms race. Signed in 2010, the treaty established transparency measures like data sharing and on-site inspections, marking the end of arms control cooperation that helped end the Cold War. The treaty's expiration follows the collapse of other key arms control agreements, including the Intermediate-Range Nuclear Forces Agreement and the Open Skies Treaty. Experts warn that the unraveling of these frameworks poses a significant threat to global security. Pope Leo has urged both countries to renew the treaty.
