How did invading Belgium, help Germany in attacking France?

The German mistreatment of Belgian civilians during the invasion was tragic. Civilians lived in a nightmare during the four years of occupation.

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
