>The Nazi were a mess, plagued with infighting, and completely incapable of measuring the strength of their opponents, which eventually led to their downfall.
no the Nazis weren't entirely a mess or completely incompetent.
There was lots of infighting, partly deliberately designed to be that way by Hitler's tactics for organizing his own subordinate leadership levels, but there was also a massive amount of military, industrial and logistical competence and a robust amount of cohesion and careful, powerful cooperation on fundamental aims.
Had there not been, the Nazi's never would have risen to power so effectively, formed their dictatorship so effectively or managed a colossal war against multiple enemies for so many years so effectively, and only been defeated at such a gargantuan cost in lives and resources. The Nazis underestimated the military strength of their enemies, but not nearly so badly as to not wage very effective war and pose a very, very serious threat to these enemies for several years.
I really suggest a book called "The Wages of Destruction: the making and breaking of the Nazi Economy" by Adam Tooze, as a nice basic primer on how wrong these ideas of supposedly incompetent Nazis are.
The above is all deviating a bit from the topic at hand but with this sidestep into a look at the Nazis, you're working from a simplistic caricature view of a more complex situation with complex evil people, and I fear that this is also all too common when many critics today view the Trump government. It's not staffed entirely by caricaturesque evil idiots. Many of its supporters are intelligent and cohesive in their guiding methodologies. (Also, no, the above isn't to compare the bad actions of Trump's government to the completely unrestrained monstrosities of the Nazis. I'm comparing defects of external analysis)
