Doubt it.
A map like this makes Russia look crushingly dominant, but in population terms, Russia has only 144 million to Ukraine's roughly 44 million: Only about 3.2x the population. Ukraine is a big country and can take a hit, as it's demonstrated for months.
Add to that:
-Gross Russian battlefield incompetence, staggering losses, depleted morale and supplies, all summed up in a disturbing new phrase I just learned yesterday: "single-use soldiers" (not exactly the battlefield tactic of a winner)
-Russian front lines stalled in Bakhmut, on the retreat everywhere else, and digging in defensive lines
-Crippling international sanctions on Russia
-Ukraine's home-field advantage (knowledge of terrain, morale boost that comes from fighting a war for survival)
-Ukraine's substantial military and financial support from the West, vs. Russia's limited international assistance coming from dubious places like Iran and North Korea
Though it will take time, I feel the likeliest outcomes here are:
-A total Russian defeat and ejection from all or almost all of Ukraine's internationally-recognized borders (Crimea being a question-mark)
-A negotiated peace
-A stalemate and "frozen conflict," just like what had already existed in the Donbas since 2014, but at a larger scale
