Actually it’s a reason they invented after the fact. The initial reason were supposed to be “Ukranian terror attacks in Russia” which were going to be false flags by Russia themselves, but UK and USA called them out on it in advance and then they invented different reasons. If they had a legitimate reason from the start it would have been the one they lead with when invading, and yet the did not.
They have lied and lied and lied, and additionally they have ALSO broken numerous ceasefires.
Putin personally want to restore old Russia, that’s the only reason for the war. He’s the one who can end it right away.
I’m not American, I don’t have any influence over that.
