What was America’s foreign policy before we became involved in WWI? What two events occurred that changed America’s thinking and led to approval of the U. S. entering the war?

Isolationism

Explanation:

America’s foreign policy before we became involved in WWI was isolationism. We became involved when Germany sunk the Lusitania, which is a British passenger ship. Another reason for involvement was the Zimmerman Telegram. Which was a letter from Germany to Mexico stating that Mexico should attack the US if the US goes to war with Germany (needed that advantage due to Mexico's proximity to the US). In return, Germany would give back Texas, New Mexico, Arizona, etc to Mexico.

the pogroms became known as kristallnacht, the "night of shattered glass," for the shattered glass from the store windows that littered the streets. the morning after the pogroms 30,000 german jewish men were arrested for the "crime" of being jewish and sent to concentration camps, where hundreds of them perished.
