States don't join, they are admitted. They are allowed into the body politic only with the permission of the other states. Same with leaving.

I would also think that states could not be forced to leave the Union against their wishes. This protects the sovereignty of a state [like Kansas] from becoming a landlocked orphan at the expense of her neighbors.

Wanna bet? Show me in the Constitution where it says that can't happen, and I'll believe you.
