Well Churchill, after his disastrous stint as the Lord of the Admiralty in WW1, had plenty of experience in what NOT to do.
At least he learned from his mistakes, and made a better fist of it in WW2.
Though he still treated the colonials as expendable cannon fodder in both wars.And the colonies too, for that matter. Ordering troops to fight in Africa, instead of defending against the Japanese.
