Frankly I wish the US
had annexed Texas. That would give us more room to carve out Slave States and continue the compromise-process until Slavery died of its own. Instead we freeze with Louisiana, President Van Buren fails in his attempt to seize Cuba (it's a miracle we still kept most of Florida and only lost the Keys!), and then the god damned plantation owners got scared by Fremont's election and we end up torn apart by years of civil war.
Virginia's economy is
still recovering from that catastrophe, I might add.
The oil would have been nice, too.
