Evolving U.S. Nuclear Strategy

The U.S. government has redefined its nuclear deterrence strategy due to shifting global threats, now including a more prominent focus on China alongside traditional adversaries like Russia. This strategic update, known as nuclear employment guidance, reflects the increasing complexity of the nuclear landscape, where both Russia and North Korea pose significant threats through expanded arsenals and modernized capabilities. Experts raise concerns about the U.S. ability to manage simultaneous nuclear challenges, particularly in scenarios where adversaries may exploit crises to amplify threats. In response, the U.S. has increased its conventional military presence in Europe and Asia, while diplomatic efforts to de-escalate tensions have largely failed to yield results.
