France was occupied by Germany because they did not resist the German invasion.
It is true that the will to resist was not strong enough. It was not like during WWI, when French fought bravely against Germans. France was decadent during the 30s. Especially the intellectual, political and military elites. The generals and commanders miserably failed in the battlefield, much to the surprise of Hitler, who expected more resistance. But the people themselves did not have enough will to fight for their freedom and their values. It was like they did not believe they could win. They were weakened.
Collaboration with the Nazis in the murders of French Jews was widespread.
There were totally unforgivable actions of collaboration with the Nazis. But active collaboration, such as denunciation, was not widespread. Most people were not heroes, that's for sure, but neither were they monsters. They tried to survive, more or less cowardly. When your army has been defeated, your country is occupied and your institutions have collapsed, it is very difficult to do anything.
France has always been hostile to Jews and to Israel despite its minor alliance with Israel when it was sticking it to the British.
Just like every other Western nation, France supports the establishment of a Fakestinian Nazi state in the heart of Israel. Not particularly more, not particularly less than the rest of Europe. French governments have also made repeated statements that more or less deny the right of Israel to protect herself. They are basically no better than the others. Of course I am completely opposed to this policy and there is no excuse for it.
Inside France, there is no persecution nor discrimination against French Jews, who are free and equal citizens. There is antisemitism among the Christian French population, but overall it is quite subdued and never takes on violent forms. There are many non-Jewish French who are very friendly to the Jewish people, who admire their faith and their culture. By far the biggest source of antisemitism comes from the Arab and African immigrants living in France (and from the leftist media that constantly bash Israel).
Also my understanding is that most French Jews are Sephardim becuase the Ashkenazim were largely wiped out in the Holocaust. The Sephardim don't have long roots in France. My Israeli friend says he hears quite a bit of French being spoken in the streets of Israel. He says many French Jews live in Israel but keep their French passport.
The proportion is approximately 65% Sephardim, 35% Ashkenazim. Yes, most Sephardim don't have long roots in France, they used to live in Arab countries under French colonial rule.
