He will never see victory, nor he will be able to take back any lost grounds from invaders, unless he changes his mind and goes for way more aggressive, distractive and violent approaches, like sending missiles into Russian heartland, moskow, or any city near the old and true borders, causing panic, suffer and damage to russian people.
Those who didn't chose this path, never managed to take back what is rightfully Thiers.
Argentina and Las Malvinas, Greece and Cyprus, Armenia and Ararat, Iran and entire Caucasus and most of central Asia, Poland and Kaliningrad, and many many more examples, are proof of my words and thoughts.
