You are demonstrating your own illiteracy once again. Prof. John. H Mearsheimer stated, that there's no question about it that this war was not caused by Russian aggression. It was caused by NATO expansion.
NATO expansion.
You seem to be in denial of the fact that NATO has been expanding.
Please educate yourself on the history of NATO, as well as NATO-Ukraine relationship, which goes back to 1991.
And stop spreading lies and anti Russian propaganda.
