<P> Canada remained focused on the European theatre, like the United States, and following VE Day was still in the process of transitioning its military force for a campaign in east Asia and the western Pacific when VJ Day arrived . </P> <P> President Roosevelt appointed the Roberts Commission, headed by U.S. Supreme Court Justice Owen Roberts, to investigate and report facts and findings with respect to the attack on Pearl Harbor . It was the first of many official investigations (nine in all). Both the Fleet commander, Rear Admiral Husband E. Kimmel, and the Army commander, Lieutenant General Walter Short (the Army had been responsible for air defense of Hawaii, including Pearl Harbor, and for general defense of the islands against hostile attack), were relieved of their commands shortly thereafter . They were accused of "dereliction of duty" by the Roberts Commission for not making reasonable defensive preparations . None of the investigations conducted during the War, nor the Congressional investigation afterward, provided enough reason to reverse those actions . The decisions of the Navy and War Departments to relieve both was controversial at the time and has remained so . However, neither was court - martialed as would normally have been the result of dereliction of duty . On May 25, 1999, the U.S. Senate voted to recommend both officers be exonerated on all charges, citing "denial to Hawaii commanders of vital intelligence available in Washington". </P> <P> A Joint Congressional Committee was also appointed, on September 14, 1945, to investigate the causes of the attack and subsequent disaster, and was convened on November 15, 1945 . </P> <P> The Japanese attack on Pearl Harbor coupled with their alliance with the Nazis and the ensuing war in the Pacific fueled anti-Japanese sentiment, racism, xenophobia, and anti-Axis sentiment in the Allied nations like never before . Japanese, Japanese - Americans and Asians having a similar physical appearance were regarded with deep seated suspicion, distrust and hostility . The attack was viewed as having been conducted in an extremely underhanded way and also as a very "treacherous" or "sneaky attack". Suspicions were further fueled by the Niihau Incident, as historian Gordon Prange stated "the rapidity with which the three resident Japanese went over to the pilot's cause" which troubled the Hawaiians . "The more pessimistic among them cited the Niihau Incident as proof that no one could trust any Japanese, even if an American citizen, not to go over to Japan if it appeared expedient ." </P>
