As everyone knows, Chavez has stated he is moving troops to the border with Colombia in reaction to Colombia's incursion into Ecuador to take out Raul Reyes, a senior leader of the FARC.
Chavez' decision to move troops is a tacit acknowledgment of his harboring FARC leaders in Venezuela. Why would you move troops to the border, unless it's to defend against a similar incursion into Venezuela? Besides, Chavez has called Reyes a good revolutionary in the past.
But this is all saber rattling at this point. The Source tells me there are no troop movements in his area on the border between Venezuela and Colombia.
