The only thing that stood out to me was that the death camps were only because they hadn't prepared for war prisoners and then they euthanized them because they didn't have enough food. I'd say that's very incorrect.
One minor point is that Churchill did not specifically pick Dresden, a subordinate did. So I wouldn't blame Churchill specifically. But even Churchill called it terrorism:
"It seems to me that the moment has come when the question of bombing of German cities
simply for the sake of increasing the TERROR, though under other pretexts, should be
reviewed."
