"If the impact of the sanctions delayed the war or forced Russia to go in with fewer supplies then the sanctions absolutely had a measurable impact."

If is key here. You claim there is no alternative to broad sanctions, yet they have been shown to not work (preventing war). And that they delayed the war, you show no proof or indications. If Putins plan was all out war from the beginning, then why would he have waited at all? And sanctions targeting special military supplies are a different thing from sanctioning the civilian population.

So what exactly is your argument based in reality?
