It was always going to be a terrible tragedy with Ukraine. Vlad committed something much worse than a crime, he committed a mistake (to paraphrase Talleyrand).

NATO+ countries aren't fighting him, they are using Ukraine as a proxy, while Vlad is fighting with his own army. NATO has been waiting nearly 80 years to attack Russia directly. They very motivated to make sure that Vlad continues making errors. As such, the longer this war takes, the better for NATO. And, unfortunately, the worse for Ukraine.

I think data collection is for sure one aspect, but I think Russian casualties is the largest motivator
