Hitler certainly made his errors. But looking strictly at military prowess, the Werhmacht was likely as good an army as there has been. I'm sure that even the Israelis study their tactics. No choice, really.
That’s very true, the Israelis primarily model their strategy and tactics after those of the Germans in both WW’s. Not surprisingly, in the 1973 war the Syrians and Egyptians followed the model of the Red Army in WWII, which was itself an adaptation of and amplification of and counter to certain aspects of German approaches. I love that line from the movie Patton — “Compared to war, all other forms of human endeavor shrink to insignificance.”
