Zelensky already offered neutrality but you always ignore that. And Putin rejected it because this was never about NATO, but about his desire for Ukrainian land and to be able to dominate Ukraine. This is brought out even more since Putin is not just satisfied with what he now has, but is demanding that Ukraine withdraw from even more land before he is ready to even start negotiations.
Ukraine, after many centuries, has freed itself from Russian domination and will not accept it again. Let that sink into your head.
What are you are babbling about?
There never has been anything neutral about the Zelensky government. It's been a NATO puppet state hostile to Russia. And, it was absolutely a national security threat to Russia.
