Well, you left out at least Dien Bien Phu (French Indochina)...that’s 5. Pretty sure they’ve gone a’piker in a couple other disasters, so the count may not be over! Tho’ with Obama as CinC, I envision a return to the top ranks by Sarkozi in no time!
I think the rankings are for the end of the season for World War II. Dien Bien Phu would be under the 'Cold' War category (French losses in Indochina, Egypt, Algeria, and arguably India. French victory over Greenpeace.)
