I see you're new here, so let me explain it to you. Operation Sealion is widely regarded as virtually impossible, though there are some on here who try to defend it. The Battle of Britain can't simply be "won", and even if somehow it is, the Germans have still got the RN to deal with. Let's be honest, Germany's surface fleet is not gonna win a fight with the Royal Navy. Now, even if the Nazis inconceivably sink most of the Royal Navy, tear apart the Royal Air Force, and cobble together the required logistical nightmare to invade Great Britain, all the while holding off the hungry Russian Bear in the East, it's still going to be incredibly difficult for them to attain a beachhead, maintain a foothold, and conquer the island against massive civilian resistance. But hell, let's assume they do all of that.
They are never, ever, ever going to be able to sail across the 3000 mile Atlantic Ocean, against a Navy created by the largest industrial base in the world, and take over a nation almost the size of Europe, and then HOLD it. I'm sorry, it just simply cannot happen.
