Vladimir Putin has warned that such a green light would mean that NATO was "at war" with Russia.

North Korea may deploy as many as 100,000 troops to aid Russia’s war on Ukraine if the alliance between Pyongyang and Moscow continues to deepen, according to people familiar with assessments made by some Group of 20 nations.

President Joe Biden authorized Ukraine to use U.S.-supplied long-range missiles inside Russia for the first time Sunday, according to multiple reports—an escalation of U.S. involvement in the conflict in response to North Korean troops being sent to aid Russia.

North Korea could deploy up to 100,000 soldiers to help the Kremlin with its war in Ukraine — a figure that could boost Russian President Vladimir Putin’s fighting force in Ukraine by up to 20%, according to a new report.

Soldiers from North Korea are reportedly fighting alongside Russia in Ukraine, and initial conflicts have emerged. A recording featuring a Russian Orthodox priest has surfaced online. In it, he claims that the Koreans "brought a plague to the country" and advises soldiers not to heed the "devilish words" of the godless.
