Guantanamo lease

Would the Government of Cuba be willing to consider leasing Guantanamo Bay to the US for a Naval Station? This may seem like a foolish question, but since the current lease is invalid, and the US cannot be ejected by force, a possible solution might be to negotiate a valid lease, to at least put the occupation on a marginally agreeable and legal foundation.

The advantages seem to be many, but most especially, if this territorial dispute can be settled in this way (and may I suggest that the UN be the bargaining representative for the nation of Cuba), possibly the Palestine question could be resolved using a similar mechanism. This would indeed be a wonderful contribution to world peace in which Cuba could lead the way.
