US criticizes Russia's new nuclear doctrine as tensions rise over Ukraine conflict

The U.S. criticized Russia's new nuclear weapons doctrine, which lowers the threshold for nuclear strikes, allowing their use in response to conventional attacks. The White House stated it sees no need to change its own nuclear posture. Russian President Vladimir Putin's formal approval of this doctrine follows U.S. President Joe Biden's reported authorization for Ukraine to use long-range weapons against targets in Russia. This development raises concerns about the potential for nuclear escalation. EU diplomat Josep Borrell also condemned Russia's nuclear threats, calling them "completely irresponsible." He emphasized that a nuclear war cannot be won and should never be fought, as discussions in Brussels focused on increasing support for Ukraine.
