So, NATO hasn't advanced into Russia then?

Just Russia advancing into the Ukraine (after promising not to if the USSR nukes were given to Russia)?

Gotcha.

Eastern Europe is not Russia and Russia does not automatically get a say in what Eastern Europe does because they are nearby. Russia seems to believe it is entitled to a sphere of influence. That the US does a milder version of what they're doing (which is also wrong) doesn't make their approach OK (or even effective).
