From a Wall Street Journal story by Ann M. Simmons headlined “Russian State Media Bolster Putin’s Narrative for Ukraine Invasion”:

MOSCOW—Russian authorities and state-controlled media outlets have issued disinformation that seeks to support President Vladimir Putin’s claims that Moscow was compelled to invade Ukraine to protect Russia’s own security.

State broadcasters, lawmakers and pro-Kremlin pundits have sought to advance Mr. Putin’s narrative that Ukraine is an aggressor that threatens Russia and the Russian-controlled territories in the Donbas, in eastern Ukraine.
