Putin Updates Nuclear Doctrine Amid Ukraine War

Russian President Vladimir Putin has signed a revised nuclear doctrine allowing for a nuclear response to conventional attacks on Russia, particularly if supported by a nuclear power. This decision follows US President Joe Biden's approval for Ukraine to use long-range missiles against targets within Russia, marking a significant escalation in the ongoing conflict. The new doctrine, which is notably timed with the 1,000th day of the Ukraine war, states that any aggression against Russia by a non-nuclear state, supported by a nuclear state, will be viewed as a collective attack. Kremlin spokesperson Dmitry Peskov emphasized that the military operation in Ukraine will continue despite Western support for Kyiv. Meanwhile, US authorities are reportedly pushing Google to divest its Chrome browser in an antitrust move, indicating a significant shift in tech regulation. This political landscape is evolving against a backdrop of rising European stock markets and fluctuating treasury yields.
