Read the passage
the attack was a great but not total, success. although the u. s. pacific fleet was shattered, |its aircraft carriers (not in port at the time of the attack) were still afloat and pearl harbor was surprisingly intact.| the shipyards, fuel storage areas, and submarine base suffered no more than slight damage. more importantly, the american people, previously divided over the issue of u. s. involvement in world war 2, rallied together with a total commitment to victory over japan and her axis partners.
