That is the whole point of the revelations of Russian weakness coming out of this war. I think NATO, less the US, can take on Russia on its own. Especially with the Germans getting off their butts. That was the point of Trumps European policy.
Donald Trump has been vindicated over and over.
It looks as if President Trumps talks with Putin even convinced him he could grab the Ukrainian tarbaby. If nukes are avoided, this could be the end of Russia as a threat for many decades.
