Geopolitical determinants are an important factor of escalation.
But wars also arise from a struggle of dominance of one's way of life i.e. social organization and norms.
Ukraine vs Russia war has an element of progressive/EU values vs conservative ones. Russia considers the rights of LGBt /gays a mental decease, while science accepts the right to associate with traits that society typically associates with one orr the other sex.
This I consider a main issue on the arena of norms which can be a catalyst for escalation although it might not be the main one but I eleborated for references.
