Russia warned in 2008 that Ukraine and Georgia would be considered “red lines” if NATO expanded into Eastern Europe. This warning was explicitly stated by Russian President Vladimir Putin in April 2008, during a speech in which he emphasized that the presence of a powerful military bloc on Russia’s borders, guided by Article 5 of the Washington Treaty, would be perceived as a direct threat to Russia’s national security.
But nice try.

Look again. Neither Ukraine nor Georgia have joined NATO. Indeed, as it has been pointed out many times, they are ineligible as long as they have a border dispute with Russia. This was known by Putin. And if this is, as you allege, about Ukraine joining NATO, why did Putin reject Zelensky's offer of no NATO in exchange for Russia leaving Ukraine? That seems to be a question that none of the pro-Russian apologists want to answer. So I guess that it is your turn to try again.
I would also suggest that you look at Putin's statements that he regrets the breakup of the Soviet Union and that Ukraine is rightly a part of Russia.
