Why did Fred korematsu argued that internment was unconstitutional?

Fred Korematsu argued that the internment of Japanese Americans during World War II was unconstitutional because it violated their rights to due process and equal protection under the law. He contended that the government’s actions were based on racial prejudice rather than legitimate national security concerns. Korematsu believed that the internment was a form of racial discrimination that unjustly targeted individuals based solely on their ethnicity, rather than any proven threat. Ultimately, his case highlighted the importance of protecting civil liberties, even in times of war.
