SUPPLY LINES not there,its only fear of missals & Rockets winning.I doubt if Russia could occupy for any length of time without resupply and logistical support .Putin planned to have a quick victory,without that he gets stuck in Ukraine and cant get back to Russia .
Its IRONIC thats what happened to the Germans that invaded Russia in WW2 ,it was a one way trip and the Russia winter caught German troops with Summer clothes and they froze to death. NOW its the opposite If the weather gets warm & muddy those Tanks had a one way trip stuck in the MUD….and become subject to those MOLOTIVE COCKTAILS that Ukrainians have been stocking.History dosent repeat but it rhymes . Ukraine just needs to buy time and hope the weather gets warm & MUDDY .Its odd that GLOBAL WARMING could save Ukraine .
Depends on Putins mental state,he still got nuclear,but that will be Russia’s demise in the end if used.
