Well, Vladimir often called American leaders Western partners. And partners, as a rule, listen to each other carefully and take each other's opinions into account.
And in this case, we again see Vladimir's amazing ability to listen carefully to America and follow its advice. For example, in the US National Security Strategy (NATIONAL SECURITY STRATEGY OCTOBER 2022, PART III: OUR GLOBAL PRIORITIES, PAGE 26) Vladimir read this -
"Russia's conventional military will have been weakened, which will likely increase Moscow's reliance on nuclear weapons in its military planning. The United States will not allow Russia, or any power, to achieve its objectives through using, or threatening to use, nuclear weapons."'.
From this, Vladimir concludes that American partners believe that he can achieve his goals "through using, or threatening to use, nuclear weapons". I think it would be impolite not to take into account the opinion of Western partners, and Vladimir is acting quite politely.
