By Spring of 1942 Germans would launch an offensive into Jordan, Syria and Iraq capturing all three.
Will they be carrying their logistic burden on magic and rainbows? Sorry, Germany needs to build the trucks and the ships to pull this off, defend the supply lines and get the oil.
Sure without Barbarossa, they can buy Soviet oil, but they need to pay for that with industrial goods while cranking out tankers, trucks, cargo aircraft, warships, warplanes, producing explosives for shells, infantry weapons etc.
Britain already has the capability to fight Germany in the middle east, the Germans have to BUILD the tools to fight so far from their bases. It's possible
with enough time but there is no way Germany will ever have enough time with America as an enemy.
And certainly not with Stalin sitting there as an enemy-in-waiting and with Britain not being completely incompetent.
Remember, relations between the Soviets and the Germans during the Nazi-Soviet pact period
were not friendly they threatened each other, shot at each other, broke the agreement for how they'd divide Eastern Europe and both sides withheld deliveries of goods. Both saw the other as an enemy they would probably need to fight and an ideological opponent. Yes, some Nazis
hoped they wouldn't have to fight the Soviets, and Stalin certainly was working to delay a Nazi-Soviet war, but there is
zero opportunity for the Nazis and Soviets to magically become buddies like the US and British acted as (and even then, the US made Britain pay for their help - the price may have been very reasonable, but even what may be the closest alliance in WW2 didn't involve in much being given away for free). The Germans
will have to buy the Soviets off and keep a rear-guard in Eastern Europe.
Even Winston "We shall fight" Churchill actually conceded that if Germany made a good enough peace offer he would give Germany overlordship over central Europe.
"The issue which the War Cabinet was called upon to settle was difficult enough without getting involved in the discussion of an issue which was quite unreal and was unlikely to arise. If Hitler was prepared to make peace on the terms of restoration of German colonies and the overlordship of Central Europe, that was one thing. But it was quite unlikely that he would make any such offer."
So yes, the position that since September 3 1939 the Wallies would accept nothing less than a march through the Reich Chancellery is completely ridiculous.
For Germany, this would mean evacuating land Germans have fought and died for to appease a power that is most remarkable for how well they've lost. There's just no way the Germans would even consider such a peace before it is too late, and Anglo-British forces in Berlin are an inevitability.
There is also the fact that if Germany doesnt declare war on the US (and God help FDR if Germany take steps to actively avoid war with the US) the US will be forced to go for Japan first. Because again, the American public will not tolerate the US waging war on an at peace Germany for the sake of balance of power geopolitics and put Japan latter.
It's highly unlikely that Germany doesn't declare war on the US though. The US was fighting an undeclared naval war against Germany before '41 and US friendship is what makes Britain truly undefeatable (though even without US friendship, the British would still be a hard fight). So declaring war against the US
must happen if Britain is to be forced to the peace table.
It's important to understand just how boxed in the Germans were by 1939, and it only gets worse after that. They didn't have the resources to fight more than one enemy at once, but after the fall of France, they have 3 extremely hard to defeat hostile powers which their cuckoo ideology and excessive ambition make hard to make friends with. For a true believer in Nazism, or even Junker-style conservatism,
invading the Soviet Union was actually the most rational of the available options.
If for some reason the Germans decide against Barbarossa, they
must focus on Britain, and to do that they have a much easier time if they can attack US-flagged shipping. (Plus, Hitler was getting pretty pissed with the game the US was playing and wanted to hurt the US back.) Reason and emotional satisfaction point the same way - as they did in OTL, only in OTL the Germans also picked a fight with the Soviets.

It's true that Hitler changed his mind often, but if you look at the war from the perspective of someone who really believes in Nazi ideology and who can't see the future, Hitler was actually a pretty rational guy (honestly, I'd say he was one of the more reasonable guys with power in Germany at that time) and in 1941, the Germans had backed themselves into a very uncomfortable corner. So while Hitler can change his mind all he likes, the situation he faces remains the same unless you invoke another PoD.
For sure the Nazis are dangerous, and things really could have gone worse than OTL. But also I think it's important to recognize that GIGO applies here. Garbage assumptions were going into the brains of these guys, so garbage actions were the output. Extremely damaging garbage actions.
