1.Slavery ended. 2. they planed to rebuild america after the war. 3. Industrialisim started.
The religion of the slaves was both visible and invisible, formally organized and spontaneously adapted. Regular Sunday worship in the local church was paralleled by illicit, or at least informal, prayer meetings on weeknights in the slave cabins. Preachers licensed by the church and hired by the master were supplemented by slave preachers licensed only by the spirit. Texts from the Bible, which most slaves could not read, were explicated by verses from the spirituals. Slaves forbidden by masters to attend church or, in some cases, even to pray, risked floggings to attend secret gatherings to worship God.
Not all all compared to the Japanese.
Considering Pearl Harbor was a Military installation, of course it was prepared to an extent, there were people that had the job of waiting for an attack, that would then man the AA guns and other defenses.
However they were not as prepared as they could have been if they knew something was coming, heck, they weren't even in the war at this point.
The Japanese had months, maybe years (I forgot) to plan this attack. It was well coordinated and obviously took a big tole on the Americans.
So no, the Americans were not that well prepared for what had come.
Hope this helps!
