I'm not French, but that's not fair. They did a lot of underground work to undermine the nazis. If you're talking about the policy of appeasement, then Neville Chamberlain -and thus the UK- is more culpable than France.
That's true. Plus the quick French defeat at the start of the war was more due to strategic errors than lack of effort. They relied on the imperviousness of the Maginot Line, the impenetrability of the Ardennes forest, and the neutrality of Belgium to protect their eastern border, and Germany invaded Belgium anyway and went through the Ardennes, rendering the Maginot Line basically useless.
