yup the Me 262 theme pop up regular in this form every year !
And deservedly gets squashed.
Hitler's stupidity notwithstanding, there is simply no way the Jumo 004 engines would have been made suitable for operational use much earlier than they were.
Once in the production pipeline, the problem wasn't the ability of the German aircraft industry to build lots of 262's but the ability of the Luftwaffe in late 1944 and 1945 to provide sufficient well-trained and experienced pilots to fly them.
Finally, the Me-262 was not a war winning plane as a fighter and was not enough superior to late war allied fighters like the P-51, P-47, or Tempest. The main advantage of its high speed was to avoid combat with allied fighters when attacking USAAF bombers. In fighter vs fighter combat, the 262's record is not all that great.
The Luftwaffe would have been better off with several thousand more Fw 190Ds.
