The factors of the landslide victory of the Nazi armies in 1940 are known. non-exhaustive list:
- A cowardly passivity and even odious complacency of Western European democracies in front of the ambitions of Hitler and the rise of the Nazi forces.
- A deep lethargy of staffs who have fallen asleep at the end of the first world war without to change their doctrine, regardless from the past conflict, not see coming technological developments. We fell asleep on its laurels for twenty years, while Hitler's Germany invented the armored division, dive bombing and parachute raid.
- A failure to take account of the psychological factor, the rage of the defeated and his desire for revenge.
- A pityful incompetence of the military thinkers in office at the time, aging and paunchy, braced on obsolete tactical and strategic plans and spending most of their time to block any modern thought (see what happened in France where de Gaulle was pretty alone to feel the wind of change ...)
- A daring and brilliant inventiveness of the Germans strategists who learned all the lessons of the WW1 and were determined to change that, even by sweeping the old concepts.
Facing this, the soldiers of western democracies had, in the best case, only their valor. Insufficent, even if not useless ...
We were fucked, in beauty, by smarter people, more daring, more inventive, more able to use their military resources and who were more determined to wage war and to win it.
Who dares wins, it is true everywhere ...
