Answer:
Germany's resumption of unrestricted submarine warfare against the United States.
Explanation:
The world War I (WWI) was a period of battle between various countries from 1914 to 1918. It started formally on the 28th of July, 1914 and ended on the 11th of November, 1918.
The key factor which prompted and influenced the decision of the United States of America to enter World War I (WWI) was because Germany resumed the use of unrestricted submarine warfare against the United States.
A subchaser also known as a submarine chaser refers to a little but very fast naval vessel which was designed specifically for anti-submarine warfare during the World War I.
During the World War II by late 1942, the German submarines (U-boats) were destroyed by the U.S Navy subchasers in the Atlantic. The subchasers that was used by the U.S Navy were the SC-497 class and PC-461 class subchasers which had anti-aircraft guns and machine guns.
The Cold War was a period of heightened military and political tensions between the United States and its allies on one side and the Soviet Union and its allies on the other. Both superpowers engaged in a variety of contests against each other, including military brinkmanship and proxy wars in smaller countries to spread their ideologies. Ultimately, the economic engine of capitalism won out and the Soviet Union collapsed.
