The idea of AmRev2 makes more sense. A few individual states here and there that attempt secession will not even get as far as the Confederacy did. Stupid idea then and now.
A second Declaration declaring independence from the new “king” would be a start and any real action would start out as tenuous as the first rev did. It is estimated that at least half of the colonists did not initially support the actions of 1775-76 and that at the end at least 1/3 still were loyalists. A sizeable portion of the population at the time laid back and rode out the conflict as best they could for as long as they could.
In the end, the goals were achieved and we ended up with a Constitutional Republic which is today in dire need of restoration.
More like AmRev3. AmRev2 was inappropriately called a “Civil War”.
The Confederacy had no designs on taking over the Federal government of the USA.
