After the war, there were two factions. Those who wanted to let them back if they voted to join back, and those who were radicalized and wanted to humiliate them while making them join the union again. Either way, reconstruction was on the way and a lot of politicians went south from the north to gain political power.

Fireside chats were effective during the war because if gave up where the enemy was. It helped our soldiers find them and kill them quicker, than it would of if there was no such thing as fireside chats. The other thing it was good for was keeping the public informed. If the public wasn't informed, then there was a greater chance of more areas being obliterated during the war from not knoeing the enemy was getting ready to strike.
Hope this helps.
