If you want to really sabotage the war effort, use the war to push for state secession from the union, particularly if you’re in a blue state. Most of the blue states are economic engines that keep the rest of the machine ticking. If they leave, or try to, that’ll be a huge kick in the nuts to any war effort.
My pet conspiracy theory is that there’s already been multiple attempts since Butler, but they aren’t being publicized because they don’t want to encourage others.
