Nuclear War

The current nuclear threat level is heightened due to a combination of factors: the potential resumption of nuclear testing by the U.S., which would undermine decades of non-proliferation efforts and could trigger a new arms race; the expiration of the New START Treaty, which leaves the world's two largest nuclear arsenals without formal constraints; and increased geopolitical tensions, particularly involving the U.S., Russia, and China, which have been exacerbated by recent military actions and rhetoric. These developments occur in a context where crisis communication channels are reduced, and nuclear doctrines are shifting towards more aggressive postures, further destabilizing global security.
