Kennedy failed. Castro succeeded.
The proof will be in the Cuban secret police files when Communism in Cuba falls.
I always believed Castro was involved. Commie files? Not sure about that. Could have been handled verbally. So we may never know.
The entire scenario has markings of higher level operative Masonry involvement. For this reason, we probably will never know the truth behind it in this world, but for this very reason, respect legitimate authority, let them play their hand and let God provide perfect justice for all, simply through faith in Christ.
