Yep Ukraine have the will to lose all the east and south for protecting their white supremacist ideal, it have the will to indebt itself to all his greedy ''ally'' for centuries to come while destroying his infrastructures and nullifying is military might.A war of attrition, ultimately comes down to who has the greatest will to win, who is willing to sacrifice the most. Do you feel that is Ukraine or Russia?
Russia have the will to spend is generation of tank that the Armata will replace losing 5% of his soldiers. It will sacrifice EU and US relation to free itself from the west to forge stronger alliances with the east.
Not sure if willing to sacrificing more is that good...
