Ya. But CA, as a new nation, will have to pay for it because it originates in the central States.
All part of the negotiations.
Also, what happens if the US decides to not honor the “water usage agreement?”
It is all part of a bargaining chip to be played and if the remaining 49 states are smart, they will get the most out of it.
The political upside is so huge Americans would be fools to fight idea this at all. Doing everything possible to make this happen is the smart play. The MBA's that infest Free Republic look at everything as a business transaction, they are stupid and ignore politics when it is convenient.
