One thing to come out of this war is that its humbled the Russians a bit and give them a bloody nose so they will think twice about ever doing anything like this in the future.
As below it would be naive to think Russia is just going to roll over and take it. IMO we are being far too complacent about that part of the equation.
The prepare for WW3 because there is know way Putin or anyone else in their government are just going to roll over and take it.
