The Uribe administration in Colombia is still trying to take the "reasonable" approach to all this, but they have referred the matter to the UNSC for discussion. So long as this can be cast as a preventative measure to counter any war-fever outbreak in the Chavez regime, it is a good move.
The willingness of Correa in Ecuador and Morales in Bolivia to echo the call for "war" should just remind any observer that ALBA (their alliance) never was intended to be a reactive defensive alliance. It is an attempt at forming a regional power bloc to isolate non-member states and then threaten them.
But that threat is still fairly weak; Hugo is still looking for the rest of his "ten battalions of tanks" that were supposed to be there the last time he ordered troops to confront Colombia... but if he keeps buying weapons, one day *soon* he might just have the means to back up his words.
Better to derail this whole ALBA scheme now, before it becomes difficult.
