Unfortunately, there isn't one. Fall back to the western parts of the country. Don't expend blood over cities that cannot be saved. End of the day, a country cannot be more than its people. Ukraine should save as many of the families (including men as it can). Eventually, the dictator and his banana republic will splinter again into even more smaller pieces than soviet union did. Current result is already written in stone when Ukraine forgo its nukes for independence and money. Sadly in current world a country's boundaries are not permanent unless backed by MAD (either on its own or through alliances). As much as we have progressed technologically, the human greed and emotions haven't changed one iota which is why we will always have wars.
