The world is on the brink of a grave moment as the expiration of the US-Russia nuclear pact, known as the New Start agreement, marks a significant setback for global peace and security. This pivotal moment comes at an especially perilous time, with the risk of nuclear weapons being used at its highest in decades. The UN Secretary-General, António Guterres, has issued a stark warning, urging the US and Russia to swiftly negotiate and sign a new nuclear arms control deal to prevent a potential global arms race. The New Start treaty, which ended on February 3rd, released both Moscow and Washington from a series of restrictions on their nuclear arsenals, raising concerns about the potential for an arms race. Guterres emphasized the importance of these treaties, stating that they have "drastically improved the security of all peoples." The dissolution of decades of progress in nuclear arms control could not come at a worse time, especially with the ongoing tensions and the threat of nuclear weapons use in the Ukraine war. Russia and the US control over 80% of the world's nuclear warheads, and the absence of binding limits on their strategic nuclear arsenals is a cause for serious alarm. The situation is further complicated by the fact that the 1970 nuclear nonproliferation treaty (NPT), which is due for review this year, could be at risk. The NPT is a cornerstone of global nuclear disarmament efforts, and its success relies on the commitment of nuclear-armed states to disarm in good faith. The New Start treaty, signed in 2010 by Barack Obama and Dmitry Medvedev, limited each side's nuclear arsenal to 1,550 deployed strategic warheads, a significant reduction from the previous limit. However, the treaty's expiration has sparked debates and concerns. Some observers attribute it to the Trump administration's approach, where career diplomats were sidelined, making it challenging to negotiate complex agreements. Trump's reluctance to extend the treaty's limits further highlights the challenges in maintaining nuclear arms control. The situation is further complicated by the involvement of other nuclear powers, such as China, which has a rapidly growing nuclear arsenal. The US Secretary of State, Marco Rubio, has called for a new agreement that includes China, recognizing the impossibility of true arms control in the 21st century without their participation. The world must act swiftly to prevent a new arms race and ensure the security and stability of all nations.
