2. PERIOD 6: 1900- PRESENT (ACCELERATING GLOBAL CHANGE AND RE-ALIGNMENT)
World War I – The U.S. Enters the War

3. The U.S. Enters the War
President Woodrow Wilson had issued the Proclamation of Neutrality
Said that U.S. would stay neutral in WWI
Supplied weapons and resources to Allies (but refused to send troops)
U.S. needs Britian and France to be victorious – so U.S. can collect debts

4. The U.S. Enters the War U-Boats
Germans used unrestricted submarine warfare = subs attacked without warning & attacked commercial ships also
1915 = a U-Boat (German Submarine) sank an American passenger liner = the Lusitania in response to British blockade
1200 people killed Americans
Result: Americans want to go to war with Germany
Wilson takes no military action

5. The Lusitania

6. The U.S. Enters the War Allied Propaganda
Americans felt receptive to it
We felt connected to England -- common language and culture
We had a friendship with France since way back when they helped us in the Revolutionary War

7. The U.S. Enters the War The Zimmerman Telegram
Intercepted by the British & given to U.S.
Sent from Germany to Mexico
Said that if Mexico supported Germany in WWI, then Germany would help Mexico get land it lost to U.S. in Mexican-American War
U.S. Declares War on Germany

8. Turning the Tide When the U.S. joined WWI, the Allies got:
More resources
More troops
Boosted morale
American involvement changed WWI
No more stalemate
Allies now had the advantage
The U.S. helped the Allies push the Germans back to the German border
