Volodymyr Zelenskyy - To the last Ukrainian

Where is the meme?

This is literally just a screenshot of a news post what the fuck

I remember in history classes (which due to my nationality and geographic position might have ben a tad biased) that a certain war stopped the second the "we fight to the last man" leader was killed, but again, by that point 95% of male population was eradicated.

I wonder how much of this is still true in modern warfare.
