The only way for any state to leave the US is via Secession and armed conflict.
Or a rewrite of the USC via Constitutional Convention which provides for exit.
Wrong. The US Constitution is silent on the issue. The last session was orderly and followed state conventions. The war came because the North acted in a fascist manner. Secession does not mean war. Only a fascist thinks like that.
“The only way for any state to leave the US is via Secession and armed conflict.”
Armed conflict wouldn’t get past the saber rattling stage, in this day and age, over a purely political question.
If Texas truly made up its mind to leave the union, Washington DC wouldn’t do more than issue a bunch of stern letters.
