So my logic here is that a Nazi Germany that is forced to seek terms in 1944 is one that is able to get rather more favourable terms out of the Western Allies and it all feeds into a more reasonable looking plan for Operation Unthinkable.
Von Moltke doesn't really want to go along with the rearmament that is asked of him and is junked in favour of Rommel, leading a National Government of quiescent conservatives and continuity fascists. This ultimately leads to the collapse of the USSR in nuclear bombardment, and the establishment of the Fourth Reich, not quite the continent spanning Greater Germany of Hitler's fever dreams but more like the Mitteleuropa fantasy of Kaiser Bill, conjoined to an emasculated and humbled (for now) Russia. Technically democratic, Germany is dominated by the NDF, which is crypto-fascist in a distinctly creepy way, especially considering Western Europeans never quite uncovered Holocaust and they have been rather too successful at pinning certain atrocities in Eastern Europe on the former Soviets.
In America, victory in '44 leads to Roosevelt standing aside and as Wallace makes his go for the Presidency, MacArthur takes his plans for an anti-Bolshevist crusade to the country. While he wins two elections in a row, he also decimates a generation in the bloodbath of Russia and condemns the Republicans to irrelevance for at least a decade. A realignment is taking place however and the New Deal coalition can only be retained for so long.
In Britain, fourteen years without a general election and a wildly unpopular war in Russia to boot leads to Labour winning a thumping majority under Bevan but the combative style of his premiership leads to him losing his majority five years later. Eden is too hopped up drugs to efficiently manage a fragile minority government however and after a fevered outburst about the Russians invading Turkestan (at American acquiescence, better them than Red China, eh?) his government crumbles and Bevan's back at least until he dies of cancer.
And finally Russia. For a good bit of time, it looked like the Russians might push the US and her Allies back to the Rhine. But the judicious use of nuclear weapons saw Stalin overturned and after a bloody scramble to Moscow, Zhukov finally gave in. The Russian State tried democracy, but elected Communists in defiance of American bludgeoning and the CIA co-sponsored a fascist coup with the Germans. For a long time, both America and Germany have seen Vonsiatsky's Russia as an ally, even a puppet. But with the old Russian Empire's border restored in Central Asia, she begins to flex her muscles and look to Eastern Europe, to the rickety principalities established in the Second Treaty of Brest-Litovsk.
And as for the Basterds. Well, they could not abide the alliance America made with the Nazis to bring down the Russkies, no they could not. Some say Aldo Raine fought for the Reds, not in defence of communism but just because he had more Nazi scalps to bag. Where they are now, nobody knows for certain, though rumours emerge now and again. The guerrilla campaign that the Turkestanis have kept up since the Russians came in is bloody and unrelenting, baring no small resemblance to certain events in Germany a couple of decades ago. Yet more rumours say they never really left Germany and wait in the shadows for a moment to strike.
The year is 1961 and Europe stands on a knife edge. Kesselring is dead and Germany has a new and radical leader who finds even the current generous peace settlement unsatisfactory. Britain has a left-wing government that may not be willing to wait for American go ahead if hostilities do break out. And in the German puppet state of Poland, some middle aged Jews with a grudge the size of the continent have got some ideas.
