Bad decisions, Oh yeah.. Like declaring War on the USA.. Remember, Germany did it first, like they really needed that huh???
But, at that moment, the first frost had frozen the Russian mud hard, and German troops were moving again, advancing on Moskow.. Victory looked imminent, to the whole world, even the Politburo was leaving the City..
Secret Negotiations were underway, to exchange western Russia, for a Ceasefire/Armistice.. It was THAT close!
Now that is a "What if".. WOW!
And, Hitler thought the Japanese would honor their Treaty, and Attack the USSR in the east.. Oopsee!
If Japan has made an Agressive move, it would have pinned Zhukov's Armies in the east,= No counterattack!
That was a HUGE error, easily equal to Stalins error depending on the Nazis to keep their treaty obligations!
I think they were both pretty equal, stupidity wise!
Possible causes of Hitlers delusional derangement, or "Idiocy"..
Advanced syphilis, contracted from a Gay Jewish Lover in his Vienna flophouse days??? Remember, Hitler was an "Artist" and existed in that community.. Many of his closest friends were Jews and Homosexuals.. Most say he "Found a Handbill" from Ostara, that turned him antisemitic/homophobic.. I think there was more than a handbill going on there.. And his odd sexual aversions started about that time as well.. It was noted by his comrades that during WW1 he never took part in an Average Soldaten's debauchery when on R&R from the Trenches..
And I'm sure his personal Quack Doctor shootin him up with Meth every day was a major factor..
Just theory.. But sure would explain much of his odd behavior and prejudices tho, huh?
