I'm sure you think you are making some sort of point in your own mind, but whatever it does in your head, it makes no impression here in the real world.
You don't "Defend" yourself by sending a 40,000 man force to invade the Capital of another country.
This whole thing was about revenge in this petty pissing contest. Nothing more.
There was no war between the North and the South. The south went to war against the United States of America. The nation that brought the world it’s greatest hope for good in the world.
Likewise the only point you’ve managed to make is “It’s my party and I’ll pout if I want to”
Congratulations.
It wasn’t “another country”.
