Putin signs new nuclear doctrine lowering response threshold for attacks on Russia

Russian President Vladimir Putin has signed a new nuclear doctrine that lowers the threshold for using nuclear weapons. The revised policy states that any conventional attack on Russia, supported by a nuclear power, will be viewed as a joint attack. This update comes after U.S. President Joe Biden allowed Ukraine to use longer-range missiles to strike targets in Russia. The new doctrine specifies that a massive aerial attack on Russia could trigger a nuclear response, broadening the conditions for nuclear use compared to the previous version. The updated doctrine also includes provisions for potential nuclear action in response to aggression against Belarus, a close ally of Russia. This marks a significant shift in Russia's nuclear strategy amid ongoing tensions in Ukraine.
