The expiring New START treaty has sparked fears of a potential nuclear arms race between the United States and Russia, which could have significant implications for global security.

Signed in 2010, the New START treaty aimed to reduce the number of deployed strategic nuclear warheads for both nations to 1,550. It also included provisions for transparency, such as data sharing, notifications, and on-site inspections. The treaty is widely considered a critical component in maintaining nuclear stability between the two nations.

With its expiration, experts warn that the collapse of vital arms control measures could lead to an uncontrolled buildup of nuclear weapons. Ukraine war tensions prompted Russia to suspend compliance with the treaty three years ago, raising concerns about the future of nuclear arms control.

On the recent discussions, Pope Leo urged both nations to renew the treaty, emphasizing the need for dialogue to prevent a renewed arms race amidst growing fears about global security and the proliferation of nuclear capabilities.

As both the US and Russia modernize their respective nuclear arsenals, the situation is further complicated by China's expansion of its own nuclear capabilities. The call for a new arms control agreement has become increasingly urgent, but no immediate actions have been observed following the treaty's lapse.

Admiral Sir Tony Radakin, former head of the British armed forces, expressed that the breakdown of these treaties represents one of the most dangerous aspects of current global security, as more countries seem inclined to pursue their own nuclear deterrents.

The future of nuclear arms control remains uncertain, but the exit of New START signals the onset of a more volatile era for international security.
