The Ukrainian soldiers are delivering their own ultimatums. Quite frequently nowadays so I am told.
IMO this war is just about over. Maybe a couple of three months. Too many mines, ISR, air support embedded in Russia's defensive capabilities.
It is inconceivable that Ukraine has the forces necessary to retake their territory. The Ukrainians know this and they also know that they are little more than doomed cannon fodder at this point.
Tragically this war never needed to happen. Brandon Nuland Britian and NATO gambled and they lost. They would have been better off to leave Germany and Russia to do friendly business and prosper. But nope. The doctrine of crippling Germany/Europe and destroying Russia was always the playbook from day one.
