Strange conclusion. In game of incomplete information showing your red line is bad. Especially so far west commit to stay outside of direct military involvement. And west cannot quit as 2.5 millions and more refugees have come. Unlike old times they are Europeans. It is all in by force. See the river by force. Hence showing your card is not the way out any more.

This is especially so as Russia has china card still can play. And gas is still pumping.

Russia strangely still assumed Ukraine will compromise and give up.

A hard game. But full information out. No.
