Political, etc
Germany: Berlin rejects Czernin’s joint peace approach to Russia.
France: Alexis Carrel, the Nobel-prize winner in Physiology or Medicine, predicts the war will last another 50 years.
United Kingdom: Lloyd George and Ribot discuss Austrian Emperor Charles’ peace letter at Folkestone, agree Italy must be consulted.
United States: U.S. Cabinet decides to prioritize sending food and money to the Allies before sending soldiers.
Brazil: Brazil severs diplomatic relations with Germany (see October 26th). (Another source already reported this as occurring on 9 April, 1917. Onehundred years after the event, it can be difficult to sort out exactly which day things happened). Yet another source states: Government breaks relations with Germany but neutral in US-German war. German Ambassador only leaves on April 27.
