History

Anyone competent wouldn't have fucking fought the russians and split their resources, they wouldn't have probably even started a real war beyond the concessions other western governments were already totally fine with giving them. A competent person would've probably just started eating up colonialist imperialist doctrine abroad, as was socially acceptable, rather than trying to fight domestically.

Like, all of what america did.

At this point in the war they were already totally fucked, so anyone competent would've negotiated for peacetime. Whether or not that would've been better is up for debate, as germany is plenty full of nazis now and they probably would've been more full of nazis had they negotiated some sort of surrender, in which they probably would've had more control over their government in order to set it up longer term.

Probably though hitler dying sooner would've been good since it would've meant hitler died sooner. Which would've been awesome.
