Should California be allowed to secede from the union?

I think every State should have the right to secede. But there needs to be a clear desire by the people in that State for secession. It would have to be done by referendum and need something like 2/3 or 3/4 of the votes to be in favor of it to go through. I don't like the idea of a State seceding by a 50.01%-49.99% vote.

Suddenly a massive Chinese fleet appears off the coast of SF and LA. It appears that the Chairman of the Dragon Party (revanchist ultranationalists who rose up after the downfall of the PRC) has found an easy target to bolster his legitimacy. What do you do?

Why worry about fictional fascists on the other side of the Pacific who might oppress them in some imaginary future, when they have real ones here in the United States promising similar things?

I've toyed with the idea that CA, WA, and OR (comprising all counties -- if the Republicans living in the arid parts of those states don't like, let them move to ID) joining Canada in a Free Trade Confederation/military cooperative so that Pacifica (or whatever you wish to call it) can benefit from Canada's exposure to the Atlantic, at the same time denying the Rump US any access to the Pacific.

All US secession movements are presently little more than wishful thinking. But what you're talking about isn't coming from nowhere:

Give us a few years of Worst Trump, especially if he disappoints all his right-wing supporters inland, and Cascadia might become a real thing.
