Here, your reasoning isn’t based on clear headed strategic reasoning (califonia’s economy would shrink to nothing out of the US, Washington state and Baja would explode) confirmation bias.
In particular, the Halo and Horn Effect.
en.m.wikipedia.org/wiki/Halo_effect
California is only strong because of it’s relation to the US. It isn’t sufficient in anything save cheese production, and the state isn’t exactly moving to embrace agriculture in its water crisis. It’s import/export market would collapse, silicon valley would instantly flee, many banks would from the pot smoking insanity if the act… you can’t build a country in the remainder population, worthless scumbags.
And your guaranteed to see NorCal break off and form it’s own state and reenter the union, if for nothing else to preserve it’s economy. It needs the US more than it needs southern california.
Didn’t I see this scenerio before, where Snake Escaped From LA?
Will everyone in LA become fishermen? Chinese don’t give rice for free, you gotta pay for that shit, and California will have NO LOANS, inheriting nasty debt and entitlement spending. How people gonna get social security and Medicare without a taxbase, after the certainty of a economic collapse, state split in two, federal government occupying San Diego, no food, no water?
If Trump marches trips in, it won’t be for occupation, but food relief convoys. Everyone would rush out to get MREs cause they are starving and beg the state to stay, and turn the water and electric flow back on, and start accepting shipping again. Californians would then hunt down in the streets with machetes everyone who wanted succession, hoping if they kill enough of them, the jobs will come back.
