# Why Did the U.S. Supreme Court Uphold Japanese American Internment During World War II?

I’m trying to understand the legal reasoning behind the Supreme Court’s decision in *Korematsu v. United States*. What arguments did the government make to defend the wartime exclusion order, and how did the Court treat the claim that it violated constitutional rights?

I’m also wondering how historians distinguish the court’s stated reasoning at the time from later assessments of the decision. If there are key documents or cases that help explain that shift, I’d appreciate recommendations.
