I've not read the report in full, but what I don't see there is an admission that Libya was already in the grip of a civil war, unlike Iraq, when we intervened with, unlike Iraq, UN backing, even tacit Russian support. Unlike Iraq, Libya already had no functioning governmental infrastructure, and therefore was always likely to need careful attention post Gaddafi.
So there are grounds for severe criticism, but it seems highly contentious to suggest that the situation in Libya is solely the result of outside intervention, or even partly. After all, we didn't - and not should we have -intervene in Syria, and that worked out ok :-)
