Risk Drivers
What is pushing the current reading.
Recent developments highlight a significant discrepancy in estimates of North Korea's nuclear arsenal, with figures ranging from 57 to 120 weapons. This uncertainty, coupled with the potential for diplomatic missteps as high-level meetings are planned, increases the risk of miscalculation. Historically, such discrepancies and the breakdown of communication channels have heightened tensions. Additionally, the modernization of nuclear arsenals and the introduction of AI in nuclear decision-making further complicate the strategic environment, potentially destabilizing established deterrence frameworks.
Risk Reduction Actions
Priority actions generated from the current analysis.
Convene a special session of the United Nations Security Council to address discrepancies in nuclear weapon estimates and reinforce non-proliferation commitments.
