US maintains nuclear strategy despite Russia's new doctrine, White House says

The White House stated that the U.S. will not change its nuclear posture following Russia's announcement to lower its threshold for a nuclear strike. The U.S. was not surprised by Russia's updated nuclear doctrine, which had been anticipated. Russian President Vladimir Putin's new doctrine allows for nuclear strikes in response to conventional attacks, especially if supported by nuclear powers. This change was formalized in a decree on Tuesday. The U.S. noted that Russia's use of North Korean troops in Ukraine represents a significant escalation. The White House criticized Russia's rhetoric as irresponsible but sees no need to adjust its own nuclear strategy.
