"The Logical Rotation of Leaders"

Raul Castro, in his first official speech as King Fidel's Prince Regent, might have misspoken slightly, or perhaps not considered his words carefully.

discussing the appointment of Salvador Valdes as the new head of the Cuban Worker's Committee, in place of Pedro Ross, who held the post for the past 17 years, Raul stated that the change was due to the "logical rotation of leaders."

oh really?

so if 17 years in charge leads to the logical conclusion that a particular leader should be rotated, then wouldn't 47 years be an even stronger logical argument that King Fidel and his Prince Regent need to be rotated too?

i can hear Raul answering, "we're not that logical."
