Putin updates nuclear doctrine to include joint attacks with nuclear support

Vladimir Putin has signed a new nuclear doctrine stating that any conventional attack on Russia, supported by a nuclear power, will be viewed as a joint attack. This change follows President Biden's decision to allow Ukraine to strike targets in Russia with U.S. missiles. The updated doctrine expands the conditions under which Russia might use nuclear weapons. It now includes responses to massive aerial attacks and emphasizes that aggression from a military bloc, like NATO, is seen as aggression against Russia itself. This revision marks a significant shift from the previous doctrine, which was more limited in its triggers for nuclear response. The new policy reflects ongoing tensions as Russia continues its military operations in Ukraine.
