Risk Drivers
What is pushing the current reading.
The current situation reflects a significant escalation in nuclear risk, driven by several factors: the U.S. is considering resuming nuclear testing, which could trigger a new arms race reminiscent of the Cold War; Japan is re-evaluating its non-nuclear stance, potentially altering regional security dynamics; and the imminent expiration of the last nuclear treaty between the U.S. and Russia further destabilizes global nuclear arms control frameworks. These developments occur in a context of modernizing arsenals, evolving nuclear doctrines, and strained communication channels, increasing the likelihood of miscalculation or conflict.
