That is why they are semi-sovereign, at best.
When King George III ceded sovereignty to the States, they were already under the Articles of Confederation -- which, by the way, stipulated to the ultimate sovereignty of the States. Which sovereignty they resumed in toto, resuming the powers they'd delegated to Congress and the Union (which existed only in the Congress), when they seceded from the Perpetual Union of the Articles, to ratify the Constitution, receding them to the new Union.
You just run down the States because you're a tyrant-worshipper.
Kiss the hand, boy. Kiss the foot. Just don't call yourself a free American. You're a subject in your own mind, so you'll never be free.
The idea that one could join a union and then withdraw at a whim, is utter nonsense.
MD,RI & TX (and perhaps some other states) declared war on the Axis powers AND commissioned armed gunboats with state naval militia and/or private gunboats under "letters of marque & reprisal".
SEVERAL of those privateers & STATE-owned GUNBOATS ACTUALLY destroyed enemy vessels & one (the gunboat Corpus Christi) actually captured a German submarine (with all the surviving crew), after a surface gun-battle that lasted several hours.
to give you an idea of how NASTY & close quarters the shooting between the gunboat & sub was, consider that MOST of the wounded/dead German sailors "suffered from BUCKSHOT or PISTOL wounds, inflicted during the fight at sea". (source the Galveston,TX County Courier.)
