Putin updates nuclear doctrine to counter perceived threats from U.S. and allies

Russian President Vladimir Putin has announced a new nuclear doctrine, allowing for nuclear deterrence against countries with large conventional arsenals or weapons of mass destruction. This update comes amid rising global security concerns and follows U.S. President Joe Biden's recent authorization for Ukraine to strike inside Russia. The revised doctrine specifically targets nations that permit attacks on Russia from their territory. This marks a significant shift in Russia's military policy, reflecting heightened tensions in the region. The announcement follows reports of increased military support for Ukraine from the U.S., escalating the ongoing conflict. The new guidelines signal a more aggressive stance from Russia in response to perceived threats.
