Well Orson my brother it's all about perspective and how you look at something..After reading what you posted I decided to ask google who defeated Germany in WW2 well of course the Battle of Britain is a top hit but that was just Germany against Britain Kudo's to Britian for winning a battle but getting the Germans to frickin SURRENDER throw down their weapons and say I QUIT! Well you're neighboring countries don't give that award to Britain So they did a survey to see what the younger generation thinks today who was most instrumental...go figure Brits think they were the most important player...but don't ask France or Germany...
Here's a link to where the survey is posted
Totally 100%

TAE. The Americans under no attack could mass produce the armaments. Those armaments were outmatched by the Germans, but they were many in number........................ Something you may find comes into play when you go up against China...........soon
I think until the P 38 Lightening that was the only time you produced something one on one that could beat the Germans. Your other planes and tanks were no match. The British armaments were a match and in some cases better. But for many reasons couldnt be produced anywhere near fast enough.
The British in a very short time of having nothing, soon became a match for the Germans and started to beat them on their own. But Britain was under attack daily from the German air force and V1 and V2 rockets.
The Germans were at the stage of being able to bomb the USA. The Germans were at the stage where their V2 variants would soon be able to reach the USA. There were within a year of producing a crude atom bomb.
Without outside help (America's) none of this could have been stopped and the Germans with an atom bomb could have beaten all opposition. The V rockets were too inaccurate to incapacitate Britain, but of course an atom bomb could. It would have probably been stalemate until a weapon like that was used and it could have been used against America as well.
Producing such a weapon is one thing and delivering it another. Also a much longer time period needed.
So America's intervention in WW2 didnt save Britains ass as your History teacher and distorted Hollywood movies tell you. But your intervention did save Britain and America from being bombed and defeated with such a weapon.
Perhaps you should ask your history teachers and Hollywood 'gung ho' movie producers how much Britain and allied forces helped America beat the Japanese in the Pacific? There were British, Australian, Kiwi, Canadian, Indian and other allied countries forces fighting the Japanese with American forces in WW2. Amy's, Airforce and Navy's. But does Hollywood ever mention this? .............Never.
History and the truth are one thing. Hollywood bollox and the distorted internet are another.
A Sherman tank up against a German Tiger tank is a really hilarious mismatch even with Brad Pitt in the turret

The Tiger could take you out at almost a mile away and even if Brad and his 2" of armoured tin can was ten yards away, he couldnt do much other than blow a track off a Tiger.
But 20, 30, or more Shermans driven by British, Canadian and French troops (with Brad Pitt in charge of course) could defeat the Tiger tank. The Germans called the Sherman tanks 'Tommie Cookers' after
who was driving them
(British troops...Tommies) and the way they just exploded into flames when hit at range.
Somehow Hollywood never shows anybody but someone with an American twang driving a Sherman tank does it?
So why do Brits think as in your survey that they did the most to defeat the Germans? Well go to Britain and you will see that most major cities are all post WW2. That is because they were levelled by the Germans and rebuilt later. It is said after the evacuation of British Troops from Dunkirk that there were no armaments for the army as they were all left on the beaches of France. This was in June 1940. All that was left was the RAF to stop the Germans. There was nobody or nothing else. All else had been defeated throughout Europe. The battle of Britain where Britain was attacked day and night by thousands of German bombers each raid, started in July 1940.
Those British and some allied pilots stopped Germany in its tracks because as Americans know, if you cant control the air space you cant win on the ground.
America lost just under 105,000 men/women in Europe in WW2.
Out of the 16 million American servicemen in WW2, only 2 million served in Europe.
Britain lost almost 400,000 men/women servicemen against the Germans.
British servicemen were over 5 million from Britain. There were others who served in Europe from Canada, Australia and others.
Britains population was almost 4 times smaller than America's back then, so a very much larger man power contribution by Britain who were defending their country as well as trying to repel the Germans from occupied Europe.
So TAE just by looking at the death figures it gives you some idea on who did most of the fighting and not what Hollywood tells you. American servicemen didnt win the war against the Germans, but their armaments which were a big contribution did.
A lot purchased by the British and not given free by the Americans.
By the way. The war was with the
Germans who in the majority adored Hitler.
I doubt you would hear anything good about Britain from the French or Germans. Brexit is a prime example. Those countries have always despised Britain and British people.
