It is not true that "Jews were guilty of nothing."
In a talk at a bookstore in Washington, DC, Dr. Jeff Herf conceded that fact to the packed audience: "The Germans had a right to be angry with Jews and to take measures to get them to leave."  check it out -- google C-Span Jeff Herf.
It is also a fact, documented in a 700-page book by his assistant, Leonard Stein, that Chaim Weizmann made a deal with the British that prolonged the war and drew in the Americans, in exchange for the Balfour Declaration of Palestine as a homeland for Jews. (Stein's book is "The Balfour Declaration." check it out.)
The impact of these two actions was that 800,000 German women and children starved to death; Germany lost a war that it had won in every other respect (see Niall Ferguson on that point); and quite significantly, Britain was bankrupted.  The British never really recovered; instead, they doubled down and refused repeated peace offers from the Germans.  USA became wealthy collecting loans in gold.
