Sure but the US and NATO had no interest in doing anything like that. Nobody gives a crap about Russia as an enemy except to the extent that they make themselves an enemy.
NATO alliance members have NATO military bases, but you're right that US and NATO have no interest in adding Ukraine as a member. As we are seeing, the country is in a weak geographic position: Russia was able to stage forces to encircle >80% of the country prior to the invasion. Who would want that kind of ally?
