WW2 Air Supremacy

At the start of World War 2 Germany had the Fockewulf a short range bomber and fighter they about in two weeks took out Poland, Denmark, Norway and other countries the short range bombers and fighters were very effective. But as the war progressed Germany realised that there short range bomber and fighters weren't doing anything to Britain or the united states. (Japan also had nothing for Long range bombers) and you'd think that Germany would build some. But they didn't and then the united states released several planes that were much better than the Fockewulf and britain did as well. Britain and the united states also had drills for oil and gas and had much more fuel than Germany. They also had long range bomber and destroyed Germany with them.
