That's great in theory but just as unrealistic in practice for California as it always has been for Texas. The single biggest stumbling block for any state to leave the union for any reason is the military. Most of the other problems can be resolved within the borders of the state, but the disposition of existing and theoretical new military hardware, personnel, and bases will always be a sticking point even assuming the federal government and the other states are willing to let them leave.

Any attempt to leave the US that has any hope of succeeding would be a very long and protracted process that would make Brexit look breakneck in comparison. We're talking at least a couple decades at a minimum.

It's either that or another civil war and that has so many variables I'm not sure anyone has any hope of predicting how that would turn out.

Leaving the union? Yep you guessed it, unconstitutional. Secession would absolutely cause a war

Republicans would absolutely love it if the most populous state that consistently sends huge numbers of Democratic representatives to DC was out of the picture. You think Democrats can’t do shit now, see what happens when you lose 40+ democrats from the House.

Don't forget they're Democrats.

When the courts rule against them they'll just meekly comply.

See my other response to peregrin5 but in addition you're assuming rational actors all around. Actual reality is far more messy with many of those involved making decisions based more on feelings than any in depth reasoning. States stay together because there's no obvious alternative. There's no mechanism for a state to leave the union and doing so requires solving many problems that have no obvious answers.

Do they have control over that? I assumed that was handled by feds

Just because Trump and his goons are ignoring it doesn't mean his cronies in congress and the supreme court won't still use it to attack anyone they want to.

yes, without any shared understanding around whether we enforce all laws or just some, law books are just reems of scratchy toilet paper. So are everyones holy books, and any international agreements we have.

Trump doesnt care about laws and law enforcement has openly hated the public for a long time. Their oaths to serve the law are a vanity that they jettison whenever its convenient.

And Biden/Harris violating god knows how many genocide and arms laws for zionist $ and then losing the election and support across every voting demographic didnt help matters. I wish I could go back in time to the day Obama picked Biden as his running mate and shake Obama until he picks someone else.

That's not actually true, there are things the federal government can do. First it's a grey area legally. The constitution says trade deals (and trade outside the borders of any one state) is the domain of the federal government.

The argument in this case would be "Is this a trade deal?". It certainly sounds like a deal, and it involves trade, but the key technicality would be if California is giving anything in return. Are they promising anything in exchange for no or reduced tariffs or are they just asking with the promise of nothing in return? If they're not promising anything there's a pretty good chance they could win the argument that this isn't a trade deal and therefore the federal government has no legal basis to intervene (although it's worth pointing out that the current administration hasn't particularly let legality influence their actions).

On the other hand if California is promising something in return there's a decent chance the federal government could successfully argue that that meets the definition of a trade deal and is therefore prohibited. This also raises the question of why another country would agree to remove tariffs from California if they aren't promising anything in return. The only answer I can come up with is to figuratively (and maybe literally at the same time) give the middle finger to Trump.
