Merkel, Macron, Bennett, et al. have asserted that Washington+London are more or less sabotaging any diplomatic solution that doesn't involve the inevitable collapse of Russia.
Russia has put their diplomatic cards on the table multiple times, including in late 2021 where they literally drafted a "security guarantee" treaty that, modulo further negotiations, Washington would simply have to sign to get Russian troops away from Ukraine. And Washington didn't even try to call a bluff, they just ignored the opportunity. Yet they constantly miscall bluffs of military escalation. Truly baffling.
It cannot be overstated how utterly nonexistent the diplomacy has been between Washington and Moscow particularly since 2014. Because one side sees the other as a fundamentally inferior state.
