You are putting forth a logical fallacy: it does not follow from something being a Kremlin talking point that it is not true. This is the classic “circumstantial ad hominem” fallacy where one avoids addressing the statement on its merits but instead distracts from the facts by focusing on the character of the speaker. Question: did the United States support the toppling of the democratically-elected, constitutionally valid government in Ukraine in 2014? As far as I can tell, the answer is ‘yes’, and this illegal change of government started a war that the current fighting is a continuation of.
Yanukovich started a crisis by rejecting EU membership, which most Ukrainians wanted, and they protested, which they were entitled to do. After killing protestors, Yanukovich, a violent coward, then panicked and fled the country. After Yanukovich fled Putin broke the 1997 treaty and invaded Ukraine. Putin was 100% responsible for starting a war, both in 2014 and 2022. The USA meddled in Ukrainian politics, but we did not force Yanukovich and Putin to do what they did. Those are just the usual Kremlin lies.
