Russian President Vladimir Putin on Tuesday approved revisions in its nuclear doctrine amid the ongoing conflict with Ukraine. The updated policy allows Russia to expand its use of atomic weapons in retaliation in case of an external assault. Putin's newly signed decree permits the use of nuclear weapons in retaliation against any significant conventional assault on Russia, including drone attacks, reported news agency Reuters.

Russia's announcement coincided with the US granting limited permission to Ukraine for the use of long-range missile strikes targeting Russian territory, notably, after Putin's warning to the West against facilitating Kyiv's attack against Moscow. What does Putin's updated nuclear doctrine say According to the updated nuclear policy, Russia will consider aggression from a non-nuclear state, especially when backed by a nuclear power state, as a coordinated attack against it and will retaliate in the same fashion. This policy revision move comes a month after Putin's earlier remarks about revising the doctrine in light of perceived threats from allied states.

Putin earlier issued stern warnings to the US and its European allies, cautioning that permitting Ukraine to strike deep within Russian territory with advanced Western weaponry could escalate tensions and lead to direct conflict with Russia..
