The fact that many chose to collaborate is not news in France. It's been a well tried (and tired) topic of many endless discussions, book, and debates.
As for the French KIAs on the Axis side, there has never been a solid number which stood the test of time. I've read from as few as 2,500 to almost 40,000. What is known, is that to this day they are NOT part of the overall casualty list in France, as French KIAs under the German banner have been denied recognition, at least thats how I vaguely remember a news article from almost 10 years ago.
I understand how you feel. I was just explaining the sentiment here in this thread and where it comes from.
Never fully realized by most people is the role, the French resistance played during the war. Many fugitive, being either resistence themselves, allied pilots or other refugees owe their life to many of those brave Frenchmen.
Although IMHO the French cannot be fully proud on their achievements in WWI (just like my own country), I would never say France was the worst. Maybe they were, but no more than any other country in 1940. Blaming them for the quick defeat is not fair. The same is for those specific individual Americans who claim they "single handedly having won the war", which you see very often in this thread and in some others as well. NAZI Germany was demolished stone for stone, one bit at the time by many countries including France.
