As a foreigner who grew up in NYC and lives south of the Mason/Dixon line
Both the Yanks and CSA had great commanders on the field of battle; both sides committed atrocities etc. War is hell, as most of us know, and the domain of hell was, during the civilwar/war between the states, within our country.
Secession from the union was due to economic reason, not slavery.
What we need is such figures as Grant and Lee, Sherman and Stonewall Jackson, and other commanders in Iraq.
I'm certain, these gentlemen would set their differences aside and fight for our country.
Secession occurred ONLY because of the fear the Slavers had that Lincoln would end slavery. There was NO other reason, don't believe that LIE. Slavers had been plotting the secession for at least a decade prior to the War.
