It was a war of maneuver from start to finish, which is why it was so much more destructive than WWI.
>Russia supposedly lost 40,000 soldiers in Ukraine last month alone
Do not believe Ukrainian numbers any more than you believe Russian numbers.
One thing we have learned from this war is that a core of genocidal right wing nationalists makes you country extremely difficult to defeat. With the current recruitment crisis in the West I wouldn't be surprised if we don't see a push from the agencies to make future generations more right wing.
