It's an older book at this point, but I keep coming back to Overy on strategic bombing. He makes a pretty solid argument that it mattered.
I'm curious what you're referring to in the pacific. I know things had a very "no prisoners" attitude, but that was mostly allied reactions to Japanese intransigence.
"Why the Allies Won" Richard Overy
Best WWII history book I have ever read and I have read thousands. It reads like a novel, but is full of historical analysis, very well cited and paints a very compelling argument.
For tips on this exact subject, check out Richard Overy's book Why the Allies Won - it's an excellent summary of why the Allies won World War II, and a number of ways that allied manpower, organization, technology, industry, and morale contributed to allied victory. Even with a super-metal, Germany could likely have caused more damage, conquered more territory, but still lost the war.
>WW2 is a perfect example of logistics winning the war.

>Turns out when you have enough bombs/napalm to remove four/five of their cities it isn't that hard to win the war.
This video is a decent introduction to the topic, mainly focusing on tank production (the part before the timestamp is about the battle of Kursk, mostly). Why The Allies Won has a chapter that's fairly in-depth about the differences in production methods as well.
Not being petty; read this book and about 70 others
