I don't blame or criticize Zelensky at all for trying to defend his people. He's literally pleading for their survival.
That said, NATO clearly understands what's at stake and continues to play it smart. They've checked themselves a few times already.
Despite the massive amount of propaganda surrounding this conflict, I still it look at through this lens: Who was the aggressor? Putin owns this 100%. If he does initiate this directive, no one knows who Zelensky is. He didn't ask for it. It's also clear now that it was simply a matter of time before Putin took this step. Fortunately, it was against a neighbor that wasn't willing to roll over.
