Why was the korematsu vs united states case important?

Korematsu vs. US was a Supreme Court case regarding the treatment of Japanese-American citizens during World War II. Shortly after the bombing of Pearl Harbor, President Franklin D. Roosevelt issued Executive Order 9066. This allowed for the US government to remove any people from their homes in military zones.

This order lead to the internment of hundreds of thousands of Japanese-American citizens. Korematsu challenged this act as unconstitutional and argued that these Japanese-American citizens were not given their 14th amendment rights.

However, the court ruled in favor of the government, stating that the safety and security of America as a whole triumphs the right of the individual.
