Look, Zelensky wasn't particularly
brave.
He believed that NATO, i.e. the USA and Europe had his back, but they never seriously did. So instead of giving up a couple of territories where the majority of the population would rather belong to Russia than to Ukraine, he expected the help from the powers that he thought were his allies, but they never intended to seriously get into a
real war with Russia. Instead, they gave Ukraine just enough weapons to be able to let the war continue with no end in sight, much like what happened when Russia invaded Afghanistan back in the 1970s and 1980s.
But now the top dog in NATO has decided to ally itself with Russia.
The metaphor of
"the leader who stood firm in his capital city as invaders with a far superior military force marched on it" is trying to achieve something that is very far from the truth. Zelensky had been led to believe that he was backed up by an even more superior military force, NATO, and he was too naive to realize that NATO would only supply justs enough weapons to keep the war going, which had also been what NATO did in the
Soviet-Afghan war: It was to be a thorn in the side of Putin, the same way that the Soviet-Afghan war had been a thorn in the side of a couple of Soviet presidents (four, I think).
