Risk Drivers
What is pushing the current reading.
The breach of the US nuclear weapons agency underscores a critical vulnerability in the cybersecurity of nuclear arsenals, which is a growing concern in the context of modernized arsenals and emerging technologies like AI and cyber warfare. This incident occurs amidst a backdrop of deteriorating arms control agreements and heightened geopolitical tensions, particularly involving major nuclear powers such as the US, China, and Russia. The lack of robust crisis communication channels further elevates the risk of miscalculation or accidental escalation, making the current environment more precarious than in previous decades.
