With due respect, your comment would benefit from a better understanding of French 20th century history. Vichy France was not Nazi rule, and it was not oppression by invaders. It was oppression of the French and by (some of) the French, albeit with significant coercion from the Nazis.
To be clear: Vichy was a client state of Nazi Germany, but from 1940 to 1942 its southern portion was not occupied. It was collaborationist, but Vichy was not simply ruled from Berlin.
It would not be accurate to imagine Vichy as an entirely foreign invention. Like in much of Europe at that time, there were many domestic supporters of reactionary conservatism and authoritarianism. As for the strength of democratic sentiment in France, remember that a President of France (and republican) once gave it only the faint praise: "republicanism is the form of government that divides France least."
The domestic political situation was in no way unique to France. There existed significant authoritarian movements and tendencies in every European country at this time. You are probably aware that both Portugal and Spain had adopted authoritarianism, and not simply by foreign imposition. My point is: the Nazis found an existing domestic reservoir of authoritarian French willing to collaborate.
Just to provide a few more facts about Vichy:
Vichy was the French government formed after invasion and occupation of northern France by Nazi Germany. Its head of government was general Philippe Petain, and Pierre Laval was its prime minister. Both had been significant domestic political figures in France. Vichy France was formed after the National Assembly voted to give full powers to Petain.
Vichy had its own paramilitary militia (the Milice) consisting of about 30,000 Frenchman. This was similar to the SS and Gestapo, but considered more dangerous by resistance French.
Of course, unoccupied Vichy adopted anti-Semitic policies and deported Jews to be murdered by the Nazis. Maurice Papon (later the prefect of police in Paris 1958-1967) participated. You can look up yourself his subsequent misdeeds during the Algerian War. Unfortunately, even after the fall of the Nazis, there continued (and continue) to be significant reactionary and authoritarian political elements in France.
