France reduced military spendings by around 30% before war. They didnt even wanted to attack Germany when their ally was attacked they just waited behind their Maginot line, leaving their ally to it's own fate.
Allies giving in to Hitlers land demands beforehand also shows how other nations didnt want new war.
You think Germans went up against countries that were ready to go ? People still had memories of WWI nobody wanted another bloodshed but Germans.
France forces where still considerable however in fact and still had more mechanised and armor divisions then the germans. however the germans did had the advantage in the air . France also had support from 300k man of the B.E.F. which where considered to be some of the best trained and equipped units at the time. What France lacked was that they didnt keep up with the new military doctrines. before 1940 they considered it impossible to attack france from the ardennes with panzer armies. they where wrong.
