The role of atomic weapons has become more prominent, and nuclear states are modernizing arsenals as geopolitical relations deteriorate, researchers said Monday, urging world leaders to "step back and reflect."
Diplomatic efforts to control nuclear arms also suffered major setbacks amid strained international relations over the conflicts in Ukraine and Gaza, the Stockholm International Peace Research Institute (SIPRI) said in its annual yearbook.
"We have not seen nuclear weapons playing such a prominent role in international relations since the Cold War," Wilfred Wan, director of SIPRI's Weapons of Mass Destruction Program, said in a statement.
