Anyone know why Guantanamo Bay Naval Base was selected?

Gitmo is not considered U.S. soil, therefore non-US citizens are not 'protected by the US Constitution.

"In 1903, the nice and snug Republic of Cuba leased to united statesa. the Naval Reservation on which the Naval Station grew to alter into into to be placed. The hire grew to alter into into negotiated to enforce an act of Congress of united statesa. approved 2 March 1901, and an appendix to this sort of the Republic of Cuba promulgated 20 could 1902. each and every and each of those contained an comparable article, to wit: "VII. That to enable united statesa. to maintain the independence of Cuba, and to guard the people thereof, as properly as its very own risk-free practices, the government of Cuba will sell or hire to united statesa. lands necessary for coaling and Naval stations at particular centred factors to be agreed upon with the aid of technique of the President of united statesa.".

I am not sure but it pisses Castro off and that is GOOD

Because politically and legally its a giant loop hole...

Because the media can't get at them to ask why they are there.
