Are we 100% certain there's no other side to what's going on between Ukraine and Russia?

Logically speaking there's been conflict between the two countries for a long time and putin said they deserve it, is he just crazy or can there be more to the story than the media says, I'm totally against what's going on in Ukraine but I feel like he probably would have done this a long time ago if he just wanted the land, i need opinion from a unsensitive perspective because what's going on is definitely not okay but I can't be the only one that feels like there's more to the story than putin just wanting the land, maybe he wasn't ready to invade until now? šŸ¤·šŸ½
