One does wonder how many of the pilots of the Armée de l'Air would aggressively fight along side of their recent conquerors. I think that the answer to that question is "very few." While the French colonial units did fight against the Allies during Operation Torch, this was in response to a direct attack by the Commonwealth and US forces against their positions. While many of the proponents of Vichy were pro-nazi (and there were certainly right-wing political groups within France that were supportive of the mass murder of Jews and other minorities and political opponents), I believe most were much more pro-Church than were the nazis. Also, I don't think that many on the French right viewed the nazis to be anything other than a tool to suppress the left, as was the case after the Franco-Prussian War.
