Victor Cha, a former director for Asian affairs at the U.S. National Security Council, has called for a new strategy to address North Korean nuclear threats.

This proposal suggests a fundamental departure from decades of U.S. foreign policy. By advocating for a "cold peace," Cha argues that the current approach to denuclearization is no longer viable and may actually increase the risk of conflict.

Cha said that the U.S. has relied on the same denuclearization framework for 30 years [1]. This specific policy approach has been pursued by seven presidential administrations [2]. According to Cha, these efforts have failed to curb the nuclear buildup of the North Korean regime.

As part of a de-escalation effort, Cha urged South Korea to halt its pre-emptive "kill chain" missile-defense system. He said this move would represent a shift toward stability rather than the strict pursuit of denuclearization. The "kill chain" is designed to detect and destroy threats before they are launched, a capability that Cha suggests could be counterproductive to achieving a cold peace.

These views were detailed during an interview aired on Foreign Affairs' YouTube channel and a related discussion at a Center for Strategic and International Studies event in Washington, D.C. The proposed strategy focuses on containment, and the management of a nuclear-armed state, rather than the unlikely goal of complete disarmament.

While some officials have rejected the idea of shifting from denuclearization to arms-control negotiations, Cha said the reality of the situation necessitates a change in tactics. He said that facing the reality of North Korea as a nuclear power is the only way to effectively manage the regional threat.

Three decades of the same denuclearization framework have passed

The proposal marks a transition from a 'zero-defect' policy of total denuclearization to a pragmatic containment model. If adopted, this would mean the U.S. and its allies would treat North Korea as a permanent nuclear power, focusing on risk mitigation and arms control rather than the removal of weapons, potentially altering the security architecture of East Asia.
