How long were american involved in world war 1

The U.S. was in World War 1 for 1 year, 7 months, and 5 days. Although, for the vast majority of 1917, America was figuring out their Draft and manufacturing runs. American troops didn't start arriving in large numbers on the Western front until February-March of 1918.

Hope this helps!

soviet influence spread across eastern europe sharply during and after wwii. the soviet armies liberated the countries in eastern europe and occupied them from the germans as they were forced to retreat towards germany.
