Counter-argument from Professor Gary Sheffield:
The counter-argument is weak when one considers that Britain lost fewer people in WW2, being in the position that it feared if it didn’t intervene in WW1.
Moreover, it didn’t put a great value on avoiding that position circa 1932 to 1939.
Yes, Europe on the Continent would have been a bit darker if Germany had won, yet people still dined outside at street cafes in Paris even under an obviously much harsher and nastier 3rd Reich circa 1940-1944.
Kaiser Wilhelm was tame compared to Hitler, and besides, what the French lived under was hardly Great Britain’s concern.
