When groups secede, it is usually for nationalistic reasons. I'm saying secession leads to a lot of geopolitical instability and usually violence and loss, for very little gain. I think multiple conflicts would arise if California tried to secede from the US. The first would be between the secessionists and federal forces. If the secessionists did not have the support of a foreign power, US federal forces would win, and even then... The second conflict would be between the "leavers" and "remainers" within California, where the remainers would initiate their sub-secessions from the breakaway state of California. Here you can imagine the awful process of Partition in India, for example; or the Serbian minority in Bosnia. And while everyone in CA is thinking they should be self-determining, we would see other political fractures. North v south. The coastal cities v the interior.
