The whole Rothschilds thing stinks of anti-Semitic slander and refusal of spendthrift bellicose nations to take responsibility. It isn't that the ruling classes were all greedy, inhumane and glory hungry that got into deep debt killing each other in petty squabbles for no lasting gain - it is our wealthy creditor's fault!
Especially since the two reason why jews were expelled were fundamentalism and avoiding paying their debts.
