Was President Roosevelt justified in ordering Executive Order 9066, which resulted in the interment of Japanese American Citizens?

He was not justified in doing so, no matter how much he was advised not to do so, President Franklin D. Roosevelt signed that order under pressure brought by Secretary of War Henry Stimson to do so, without measuring the consequences that this would bring, such as the isolation in specific areas of American people of Japanese origin for considering them highly dangerous in the face of attacks in Pearl Harbor, as well as other subsequent hand attacks. This measure created xenophobia towards the Japanese because with it there was incitement to racial prejudices by the Americans.
