Yep. The Germans really shot themselves in the foot. Ideology trumped pragmatism and common sense for those jackasses.
Supposedly, Hitler was skeptical of nuclear weaponry and power (which he regarded as "Jewish science."). But, when it came to aeronautics, jet engines, and rockets, they were probably a decade ahead of everyone, including us. If left alone, Von Braun and his crew would have developed rockets that could hit our East Coast--and with big payloads. And their jet airplanes would have owned the skies. The Nazis had to be taken out, and within a set window of time, before they could develop technology (and mass produce it) that could win the war for them.
