Today’s international climate is marked by heightened tensions and evolving geopolitical dynamics. However, the record leaves little room for doubt: testing has come to an almost complete halt, and States continue to support and use the verification system . This reflects a near-universal view that nuclear testing has no place in the twenty-first century .
