Battle of Britain: Failure

OK, this is mildly involved topic, so get comfy.
Awhile ago on PBS, I saw this "documentary" about how Germany could've won World War II. It went in depth about the special forces Churchill ordered to pester the occupying forces, though they weren't designed to live for more than a few weeks. The main jist of the program is, Operation Sealowe is successful, and by using the same tactics they used in France, Germany conquers Britain. That in itself was about 40 minutes of the program, so I don't remember mush of it. An interesting point I do remember was Germany would keep the populace under control by using duty tactics, "Herr Officer, yes that silly little cross has replaced the Union Jack everywhere, but you still have a duty to protect and serve your people." With Britain taken care of, no reinforcements are ever sent to the Balkans to confront Mussolini's forces, thereby never tying down the Wehrmacht to assist them. Hitler invites all the World leaders to his art museum in Linz, but it is a distraction. Simultaneously, Germany now launches an all out assault on Russia, as originally scheduled. Moscow is taken, and Hitler dominates all his opponents, except that itty bitty country with three letters. With the US of A completing it's Manhattan project, and Germany refining V2s, the two superpowers call it a truce, and a Cold War different to the one we know begins. And because Germany was never defeated, all of its top scientist are never forced to work for NASA. The program concludes with a picture showing that famous picture of the man on the moon, except the flag isn't the stars and stripes and the astronaut has this peculiar armband.
As some of you may know, I've been planning to make a World War II "mod" for this nifty little strategy game I have. Well, I thought yesterday that as far as games go, World War II is a tired subject, so why not make something where it's the dawn of the 21st century and the US, Germany and a resistance group all go to war? While sparing you the details, Germany conquers almost all of Africa as no other European countries are there to colonize it. The US and Germany go to war (Hitler's died by now) and the African resistance attempt to free themselves.
For any of this to take flight, the Battle of Britain must be lost, sorry Britons.
How, could this have most feasibly happened and what would
Part I
