Russia updates nuclear doctrine, lowering threshold for atomic weapon use

Russian President Vladimir Putin has signed a new version of the country's nuclear doctrine, which lowers the threshold for using nuclear weapons. The updated policy allows for a nuclear response to conventional attacks, especially if backed by a nuclear power. The revised doctrine specifies conditions under which Russia could use its nuclear arsenal, including responses to attacks on its territory or critical military facilities. Kremlin officials have indicated that strikes by Ukraine using Western-supplied missiles could trigger such a response. While the U.S. has not observed any changes in Russia's nuclear posture, the new doctrine reflects a more aggressive stance. Experts note that this development could escalate tensions, particularly regarding Ukraine's military actions against Russia.
