I think you mean a Ft. Sumter moment.
No, I meant a 1776 moment. The civil war was a regional group of states which as a whole were persuaded to secede and fight for a very specific reason: retention of slavery by the ruling class of that time. The “enemy” was demonized to bring the common man into the fight using the same tactics as the democrat party uses today. For a CW you need to have coherent and large support in all of the states involved with a great degree of regional coherence or it will be beaten down faster than the old confederacy.
A rev is an overall movement that includes and builds on support in all parts of the country to put aside the current ruling class and in this case to reestablish the Constitution and the Republic, NOT to establish a new constitution and confederation of states. A rev may take years as we have seen throughout history and is not the easy way to go.
In a rev the supporters risk failure and loss of life and treasure but they press forward knowing the risks and knowing the importance of the cause. They also understand from the start that they may lose, but the benefits to all of success again moves them forward. If I pick up the flag I move forward and if I fall I look to the person to my left or right or behind me to pick up that flag and keep moving forward.
