Is Volodymyr Zelenskyy one of the greatest leaders of all time?

[President Punxsutawney Phil]

No. This is typical early-war rhetoric where we allow our emotions to take over and get swept up by the narrative. His stand in Kyiv is admirable, and he is showing far more bravery than your typical national leader, but the greatest leaders of all time are a very exclusive club with a very high bar to merit entry.

This.
(And I'm saying this as someone who admires the figure he cuts politically)

[President Punxsutawney Phil]

Zelensky is a clown who has repeatedly undermined his country's position and antagonized his allies in the months prior to this conflict, but he is very good at playing a leader on television.

Which is a huge part of actual leadership in a modern war. The Mother Night "we are what we pretend to be" quote comes to mind. Right now, Zelensky is indeed pretending to be Ukrainian Churchill.

Not at all disagreeing. You agree Ukrainian Churchill is exactly what Ukraine needs right now, no?
