Having lived through war and having family fighting it gives one perspective unseen by bulk of the Amrican. with the attack on Pearl Harbor there was justifiable fear of a Japanese invasion on the Pacific coast.
Pearl Harbor sneak attack was first of many blunders by the Japanese. The second was the failure to follow up. Even with 3 aircraft carries, the navy could have been brushed aside and IJN could have sailed into San Francisco Bay and established a beach head that would have paralyzed the USA.
However, as in many instances the IJN failed to follow through.
For us civilians, besides loosing loved ones killed in action or those became POWs and, of course lives lost through incompetent blunders; there were ration books, no tires, gas rationing and victory speed limits.
However, the war was a boon for women and blacks who manned the arms factories and shipyards to supply our armed forces and those of the USSR and the British Empire.
My aunt wound armatures for Sherman tanks while uncle was a communication sergeant with AAFC and took part in the invasions of North Africa, Sicily and Italy. Cousins, one a bomber pilot in the UK and another as gunner on a B25 shot down over Germany and as a POW
