So what's the alternative, don't support Ukraine and let Russia finish their invasion? Arming the defender against an illegal aggression is not aggression itself.
Intelligence agencies will say anything. Everyone crafting pet conspiracy theories today belies either underlying motive or incompetence. (I tend to assume the latter.) It’s in the same category as same-day armchair crash investigation. Fact-driven analysis not yet possible, the discussion gets dominated by those fitting data to their worldviews.
