As far as losing his country, the entire world thought Putin would take the entire country in a few days.
Yet because of Zelinsky's intelligence and bravery and the incredible motivation and drive for survival against genocide of the Ukrainian people, Ukraine has resisted a much bigger population country for years already!
Ukraine would have won by now if the west hadn't put absurd restrictions on the timing of weapons, types of weapons, and stupid rules about using the weapons against military targets in Russia.
Indeed the maga fascists led by Putin's poodle Trump and Trump's toady religious fanatic speaker Johnson blocked all aid to Ukraine for EIGHT MONTHS! Criminal. Blood is on Trump's petite hands.

Also at that same time Russia dug deep with stealth Russian soldiers in Donbass. etc.
