In The World Crisis, Churchill, the Dardanelles disaster in mind, wrote: “[T]he terrible Ifs accumulate.” If Britain had not issued the war guarantee and then declared war on Germany, Hitler might never have invaded France. Had he not, Mussolini would never have invaded France or Greece, or declared war on England. With no war in the west, all the Jews of Norway, Denmark, Holland, Belgium, Luxembourg, France, Italy, Yugoslavia, and Greece might have survived a German-Polish or Nazi-Soviet war, as the Jews of Spain, Portugal, Sweden, and Switzerland survived.
