Putin updates nuclear doctrine amid rising tensions with Ukraine and the West

Vladimir Putin has updated Russia's nuclear doctrine, allowing for a nuclear response to conventional attacks supported by nuclear powers. This change follows U.S. support for Ukraine's ability to strike inside Russian territory with longer-range missiles. The new doctrine, outlined in a document on nuclear deterrence, broadens the circumstances under which Russia might use nuclear weapons. It reflects a shift in strategy, relaxing the threshold for nuclear engagement in response to perceived threats. Russian officials, including Foreign Minister Sergey Lavrov, have indicated that recent Ukrainian actions represent an escalation. They urge Western nations to take note of Russia's revised stance on nuclear policy.
