I doubt that Fidel will ever come back to power. I think he is slowly going to the great beyond. Too slowly. . . he could have gone a long time ago.
Choose your leaders with wisdom and forethought. To be led by a coward is to be controlled by all that the coward fears. To be led by a fool is to be led by the opportunists who control the fool. To be led by a thief is to offer up your most precious treasures to be stolen. To be led by a liar is to ask to be told lies. To be led by a tyrant is to sell yourself and those you love into slavery.
