Agreed LLogan. Had the Germans focused work on a single type of fighter, the Fw-190 and 262 for example, instead of all of these radical projects, things could have been different, at least prolonged.
But I think its all tied together, too. Taking away the ability to produce weapons certainly puts pressure on all of the other aspects of making war, including developing technology. If anything, the destruction of Germany's industrial capacity sped the technology along, as they were desperately trying to find something to turn the tide.
Fortunately, the scientists that left Germany robbed the Nazi party of huge advances in technology that may have impacted the outcome, or most likely, duration, of the war.
