Russia and the US.

As long as this is a war of attrition, Ukraine is done without US support.
Russia and America talk about Ukraine, not so much to or with Ukraine.
Europe plays no role. And if it wanted it diferrenbtly, it nevertehless would not be able. Realostically Eurpoe cna send 10-20 thousand instead of the calculated 100 to 150 thousands "peace keepers" that would be needed for a Euro msision in Ukraine. And it would need plenty of US capabilities that Europe simply does not have.
So, in the end Washington and Moscow not only tlak abotu and not with Ukriane, but they also talk
about and not really with Europe.
Putin is a happy man currently. Nothing but wins this week.
Europe is staring into an abyss now. At the very bottomg, deep deep below, there lie the many broken monuments of its own security-political failures and omissions. And the whining sound you hear is not the wind, but Merkel's giggle.
