The article addresses the historical context of warfare in the 20th century and the mechanisms developed during that period to regulate conflicts and prevent nuclear confrontation. It specifically mentions the expiration of the New START treaty on February 5, which was the last treaty between the United States and Russia focused on arms control. This event marks a significant shift in the landscape of global nuclear disarmament, as several other treaties have also been abandoned by both countries in recent years, leading to increased tensions.

The New START treaty was vital for international security as it represented the last applicable framework for global arms control amidst a disintegrating landscape that has persisted for two decades. Its expiration without any replacement positions the world in a precarious situation not seen for half a century, as it raises concerns about the balance of nuclear power and the potential for escalation in arms races. As the article notes, this could lead to more aggressive postures from nuclear states, further complicating the geopolitical climate.

The expiration of the New START treaty and previous withdrawals from other arms control agreements signal a crucial juncture in international relations. The lack of a robust framework for nuclear arms control diminishes the prospects for diplomatic resolution of conflicts and increases the likelihood of confrontation. This context is particularly alarming given the global geopolitical tensions that have surfaced, and without constructive dialogue or new agreements, the risk of catastrophic conflict may increase significantly.
