The recent behavior of Western diplomats, including walking away from the negotiating table the moment the Russian delegation expresses their views on the Ukraine/Russia conflict during an OSCE PC meeting, signals a "tough" stance towards Russia.
This approach suggests that the West is not willing to compromise on key issues and is becoming less optimistic about the possibility of reaching a peaceful resolution to the conflict.
It remains to be seen how this increased tension will affect future negotiations and potential solutions to the ongoing conflict.
