I understand that bombers played a huge role, just pointing out that the Germans had plenty left as the war carried on. Also it seemed to me that you meant to say the Brits produced more fighters than the Germans, which overall isn’t true. There’s also a difference in approach/strategy in there too. But if they never invaded Russia and didn’t have to deal with the US (America likely drastically cuts its supply to GB if fighting Japan without a German declaration of war), combined with not undestimating the RAF a 2nd time around (which was a huge part of the issue strategy wise the 1st time around) it’s very likely the outcome is different. I won’t guarantee a German victory, again noting that the RAF and Royal Navy were tough as nails, but I’d lean towards saying the % of Germany taking it is higher than them losing.
Germany was hurting for resources in the war that actually played out, but continued to fight for years on multiple fronts. They gain even more time/resources if they’re just concentrating on GB and no one else. Once again, as I pointed out with the Russians.. there’s a reason GB was pounding the table and pulling its hair out trying to find a way to get the US directly involved in the war, GB was running on fumes but was also fighting for its life so they dialed everything up to 11 and were willing to die rather than surrender. But Germany was also working on things like rocket/missle tech that could have been better perfected and used to greater effect in a hypothetical scenario like this one (for example).
