Did the allies win the second world war or did Hitler lose it?

In some ways you are correct but the answer you are looking for depends on when you ask it-the German Navy actually choose correctly as far as the breakdown between surface and submarines went because the carriers need protection and the German Navy was not large enough to protect them and while they could have produced more submarines and cut back the larger ships there is a "pride" issue; carriers would have been of limited value and using them against the UK was not a good bet-carriers are good for some things but putting them near England and using them would have been suicide. Lack of long heavy range bombers was the weakness of the Luftwaffe-they had very good shorter range/medium bombers but not any real heavy bombers.. Changing the air war against Britain from the air field to London was a mistake but not because of British bombers the Germans were actually attacking the fighter fields and if they had continued that they would have destroyed British air defenses and then been able to bomb other targets easier. The Battle of the Bulge was a last try to win and if it had worked would have given Germany more time but the Germans were already losing at that point. Hitler did lose the war in many ways by not listening the German High Command on the timing and targets of the strike against Russia (Operation Barbarossa) and that decision really made a major difference in the war and in not supporting Rommel and the African campaign which was tied to the timing and his wishes on how the campaign against Russian was to be done..
