Immature and inaccurate comments like this one do not add much to the conversation.
Strategically, the South had one major advantage--they only had to avoid losing, they did not have to win outright.
Logistically, the South had all the disadvantages--little industry, no shipyards, etc.
The South had a huge advantage in military leadership: Lee, Jackson, Longstreet, Johnston, Forrest, Stuart, etc. This was only changed after Grant, Sherman, Hancock, Chamberlain, and Sheridan rose to the top.
The North had a similar advantage in political leadership--Lincoln over Davis.
As late as the Spring and Summer of 1864, the outcome was in doubt because the war was so unpopular in the North. And, the North narrowly avoided annihilation at the Battle of the Wilderness. Had Longstreet (whose flack attack was rolling up the Northern lines "like a wet blanket") not gotten shot at a critical time of the battle, that battle would have been Grant's first and last in the East.
A couple of victories by Grant, and the entire Army voting saved Lincoln's political hide and prevented a negotiated peace.
The bellicose and ignorant things that some have written on this board are unworthy of the men who fought on both sides. And, they do not sound at all like the things the men themselves wrote.
