Perhaps it's time we looked at a few facts here.
1. In 1939, the French and British were the only two countries who fully realised the threat posed to Western civilisation by Germany. In all fairness it has to be said that Roosevelt, too, realised what was what, but it took the US public two years, a kick up the arse from Japan and the subsequent declaration of war by Germany on the USA to get the picture.
2. During the Battle of France in the summer of 1940, France lost 130,000 dead. To put that into perspective, this was more that the US lost from all causes (death, wounds, desertion etc.) during the whole Normandy campaign, or the 256,000 dead of Britain over the whole course of the war. The French leaders, out-generalled and with memories of the bloodbath of WW1 elected to save lives and retain control of at least some French territory by seeking an armistice.
It is perhaps salutary to remember that the French army was not the only one defeated by the (numerically inferior) Germans that summer. But one other army was able, by dint of abandoniong all its equipment, to scramble back across the Channel and defend their island by sea and air until it could be used as a springboard for the invasion and liberation of the Continent.
Free French forces fought with notable distinction at, for example, Bir Hakeim during the Alamein campaign, at Monte Cassino under General Juin (probably the most competent general of all during that campaign) and during the advance up France following the invasion of southern France under General Le Clerc.
3. The French fought with notable bravery (as is their wont) in Vietnam - e.g. at Dien Bien Phu - but let us remind ourselves that they were not the only major power to be ultimately defeated by a ragged-arsed peasant army there.
Knocking France is a pretty cheap way of getting laughs - and betrays a sad ignorance of history.
