The Real Threat of Putin's Tactical Nuclear Weapons Deployment.

President Joe Biden has warned that the threat of Russian President Vladimir Putin using tactical nuclear weapons is "real" after Russia deployed its first tactical nuclear weapons to Belarus. The United States has said it has no intention of altering its stance on strategic nuclear weapons in response to the deployment and has not seen any signs that Russia is preparing to use a nuclear weapon. The Russian deployment is being watched closely by the United States and its allies as well as by China, which has repeatedly cautioned against the use of nuclear weapons in the war in Ukraine.
