The sentiment in Washington before the Moscow attack was that Russians needed to experience firsthand the impact of the war in Ukraine. This attitude intensified as US sanctions proved ineffective, Russian advancements in Ukraine quickened, and President Putin received a high level of support from the Russian population during recent elections.
Previous attempts to make Russians understand the war’s effects included drone strikes on major city centers, attacks on infrastructure, and efforts to destabilize Russia’s economy.
What then doesn’t matter, the point of the quote is that she’s actively promoting terrorism.
