It’s in spanish, but according to Prensa Libre, a Guatemalan newspaper (http://www.prensalibre.com/pl/2009/septiembre/22/343810.html), a Venezuelan plane arrived carrying 16 tons of food supplies for needy families in Guatemala. Apparently there is a drought going on in Guatemala. Now it could be the same plane, or a cover for other planes.
I doubt it. This is how many of these military operations take place, especially operations by Russian trained special forces.
your post sounds very logic. Maybe Ego Chabeast is not that dumb to attempt an invasion by himself.
