Russia updates nuclear doctrine to lower threshold for use of atomic weapons

Russian President Vladimir Putin has signed a revised nuclear doctrine that lowers the threshold for using nuclear weapons. This change allows for a nuclear response to conventional attacks, including those from Ukraine using U.S.-supplied missiles. The updated doctrine specifies that Russia could use nuclear weapons if it faces aggression from non-nuclear powers supported by nuclear states. This marks a shift in how Russia defines threats to its sovereignty, particularly in light of recent missile strikes on Russian territory. Experts suggest that while the new doctrine clarifies Russia's stance, the likelihood of an actual nuclear response remains low. Analysts believe the revisions are more about signaling than a significant change in policy, as Putin has previously used nuclear threats without following through.
