Putin signs new nuclear doctrine lowering threshold for use of nuclear weapons

President Vladimir Putin has signed a new nuclear doctrine that lowers the threshold for Russia's use of nuclear weapons. This change follows the U.S. decision to allow Ukraine to strike targets in Russia with longer-range missiles. The updated doctrine states that Russia may respond with nuclear force to conventional attacks supported by nuclear powers. It broadens the conditions under which nuclear weapons could be used, including responses to massive aerial attacks. The new policy reflects Russia's ongoing military challenges and aims to deter Western support for Ukraine. It emphasizes that any aggression against Russia, especially involving NATO, will be viewed as a collective threat.
