The ARTIC League was just a "symbolic" sort of name, complete fiction, a good dose of northern unity would cause (in HOI2 terms) these countries to be something other than victims. The only way in HOI2 to make minors anything other than a pushover (especially later in the game, 45ish) IMHO is to ally them into regional bands. Could have happened in any number of wars previous to the big one. I figured since we were starting from just before the civil war I had a few decades to play with.
"The south did not accept blacks in their army. The north did, though, but when the south caught these blacks a PoWs they were executed on spot without trial".
Come on man...
Actually the south DID allow blacks in their army and blacks themselves even formed several all black regiments. There were numerous blacks present in "official" signed capacities in CSA units and indeed they fought heroicly, not to mention the blacks present to provide logistical support for the confederate army. Too late in the war, Robert E Lee himself proposed granted freedom to all blacks who would fight. It was declined as a moot point by then. BTW, the north did not allow blacks into their army until 1863 in their sudden quest for moral high-ground in a failing military operation.
Certainly there were atrocities commited against POWs.... on both sides!
But, if you want to talk about atrocities, how about the organized robbery, rape, and murder commited on a national scale by the Union Army against black and white southerners, who were admitted "their" own citizens? Everyone in the south was starving, so the loss of federal prisoners at Andersonville were attrocious but there was a reason... no food. However, it was not the worst prison camp of the civil war... You have to look at Palmyra, Illinois for that war crime...
Anti-southern bias in the media is nothing new, so your understanding may be excused by the public education system. However, your (and most peoples) misconceptions are certainly not backed up by the historical record. "To the victor, go the spoils" the sweetest of which is getting to put your slant on the history books!
