Putin updates nuclear doctrine to include responses to conventional attacks supported by nuclear powers

President 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 comes as the U.S. allows Ukraine to use longer-range 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 broadens the triggers for nuclear response compared to the previous doctrine, which was more limited. The changes reflect ongoing tensions as Russia continues its military operations in Ukraine.
