Are there practical differences between ownership and indefinite lease? I mean can the lease be cancelled or terms changed unilaterally?

The Castro government doesn't recognize the lease as legal. So at least in some sense it is being maintained unilaterally.

(I'm having trouble finding something to link that is not charged, but I think that is a fair characterization of it)

ownership != sovereign soil

Again what are the practical differences? All I can find is stuff about mineral rights.

The practical difference is that any laws regulating the kinds of things that can be done on US soil do not apply to Guantanamo Bay.
