See here.

That poll surprised me, I would have expected the opposite results. It seems counterintuitive to me that the French wouldn't see the American/British/Canadian forces literally fighting town to town to liberate their country as the ones who most contributed to Germany's defeat.

Likewise, it seems like post-Cold War there's a much greater appreciation for Russias role in defeating Nazi Germany, yet the French as of 1994 overwhelmingly changed their opinion about who contributed the most to the victory.

Can anyone provide some insight as to why this is?
