I've never read a sentence that so clearly ignores the meaning of the words it is rejecting. When NATO includes another country, it's expanding. This is the meaning of the word "expand", to grow - adding a new country to your territory makes you grow - or expand!!

As Ukraine (as well as the Baltic states, which are already NATO) borders Russia, "expanding to the Russian borders" describes physically what it is that NATO is doing.

I use words with their current meaning without trying to spin their meaning to express something that's occurring... if you think that's a "deffective world view" then you're way too far into the play of words of politics to be able to have a serious discussion about the topic.
