They are certainly NOT co-sovereign, that is an absurd statement as states cannot leave the Union. Any sovereign party can withdraw from a treaty. The states are represented in their ability to collectively steer the federal government by Congress and the Electoral College. The feds are currently enforcing the ill will of both which sadly is the result of last elections.
I said co-sovereign, not that they're both independently sovereign (required for your treaty example). This is straightforward law, go read up on it. States are considered sovereign themselves, with powers limited by the US Constitution - the same qualification as the Federal government.
It's honestly besides the point. For even if I accept their sovereignty, they have exercised their sovereign will in the Electoral College to elect this administration. And they always have the power to impeach it through their representatives, the administration did not take that away, nor did they suspend the Congress, nor do they appear to be preparing to wrongfully influence the next elections. A state can not go and rebel against the Union because it disagrees with the current administration. Hell, the Union can literally change the Constitution against the will of a particular state if enough other states agree. You can consider states sovereign if you want, and I concede that it's an established tradition, but when the whole agreement on the separation of powers can be changed with a particular state voting against it - that's a mockery of sovereignty of that state.
Sorry, this is a whole ball of post-hoc motivated reasoning.

Simply repeating the word "sovereign" doesn't mean you've applied and fully accounted for the definition.
> A state can not go and rebel against the Union
I'm not talking about rebellion here, but the provision of law and order in spite of the federal government's policies of repeated lawbreaking.

This subject is not like computer programming where finding some lever you can pull to affect an axiomatic-deductive result invalidates the independent meaning of the original thing. If two-thirds of the states actually wanted to scrap the current Constitution and turn the federal government into an autocracy with two impotent patronage-review councils, then you would have a point. As it stands, you do not - the entire point of these necessary supermajorities is to put the brakes and pull us towards a foundation of individual liberty and limited government when things are close to evenly divided.
As I said, you really need to read up on the founding of this country. It's got all of these dynamics and more - including the "liberal media".
