Ukraine has reportedly launched strikes against Russia using advanced US missiles, according to the Russian Defense Ministry. Amid these developments, President Vladimir Putin signed a new nuclear doctrine threatening to use nuclear weapons if nuclear powers participate in missile attacks on Russia. Russian Foreign Minister Sergei Lavrov characterized this attack as a sign of Western escalation, while the Kremlin’s messaging remains contradictory. Experts suggest that Putin’s threats are intended to deter the West rather than indicate an actual intention to deploy nuclear weapons.
