The New START Treaty, the last remaining major nuclear arms control agreement between the United States and Russia, officially expired today. The end of the treaty removes limitations on the number of strategic nuclear weapons the two countries can deploy, raising concerns about a new era of nuclear arms competition.
The development marks a significant shift in the global security landscape, introducing a new layer of long-term geopolitical uncertainty. The treaty's expiration means there will no longer be a framework for mutual inspections or limits on the buildup of the world's two largest nuclear arsenals, a situation that foreign policy experts have warned could make the world inherently more dangerous.
