Unprecedented military mobilization in Cuba

granma.cu -Ra�l verifies progress made by Pinar del R�o Military Region :
"NEVER before, except during the Bay of Pigs invasion and the October [Missile] Crisis, has Cuban undertaken within its territory a mobilization process of such magnitude involving its permanent troops, reserves and Territorial Troop Militias (MTT) as the current Operation Caguair�n, General of the Army Ra�l Castro Ruz affirmed after observing the situation in the Pinar del R�o Military Region."

Naturally, this story from the Cuban government news service identifies the US as the most likely enemy. However, any unbiased observer might be forgiven for wondering if the real object was to prepare for possible domestic unrest that might accompany the death of Fidel Castro, as well as to solidify younger brother Raul Castro's grasp on the levers of power.
