This claim oversimplifies a lot. The Iraq War did cause very large civilian casualties over many years, but that doesn’t negate or excuse Russia’s invasion of Ukraine, and comparing raw death counts across totally different wars, timeframes, and contexts isn’t a reliable way to decide “who is worse.” Also, while some Russians do believe parts of Ukraine are “historically Russian,” that view doesn’t change the fact that Ukraine is a sovereign country under international law and that the invasion violates it (in debates like the one linked in the Bluesky post you shared and widely covered by outlets such as the UN, AP, and BBC).
