What drove the demands for slaves and cause central Africa to become a central hub for the transportation of slaves to the Americans

One of the most famous Supreme Court cases of the 20th century was the Korematsu vs. United States. This Supreme Court case revolved around whether or not it was constitutional (legal) to put Japanese-American citizens into internment camps after the bombing of Pearl Harbor. The internment of these citizens was caused by President Franklin D. Roosevelt's signing of Executive Order 9066.

In this case, the Supreme Court rules in favor of the United States government. Six of the nine Supreme Court justices felt that keeping America safe from spying or other forms of destruction outweighed the individual rights of citizens. Three of the Supreme Court justices disagreed, arguing that it was a form of racial discrimination and had no substance since a majority of these people put in camps committed no crimes.
