We still haven't heard one peep from the commercial media/entertainment news corporations (even the simple fact that something's happening), but Mark Vorpahl has written an articulate and persuasive description of what's really behind the U.S. flotilla en route to the southern Caribbean (Mare Nostrum, or our "Fourth Shore"), "The U. S. Military Moves Into Costa Rica".
I am entirely in agreement with his conclusions. Anyone who would prefer not to be completely surprised by another shooting war, or the next U.S.-backed coup attempt, should read what he has to say.
Most of these measures [recent U.S. military operations in Central and northern South America] have been justified on the grounds of combating drug trafficking, including the military buildup in Costa Rica. However, they have not curtailed this problem at all. Such U.S. military buildups have generally been accompanied by an increase in drug trafficking, as has happened in both Columbia and Afghanistan. Based on this record it can only be concluded that the "War on Drugs" rationale is a red herring for public relations consumption, not the actual motivation.
This military build up in Costa Rica is the latest in a series of moves the U.S. has made in Latin America that seeks to use threats and arms to reverse the strength of popular anti-imperialist forces across the region. The U.S. is playing with the possibility of erupting a continental conflagration for the sake of corporate profits.
While it is doubtful that the U.S. wants to directly engage in a military conflict with, most likely, Venezuela right now, preparations for this possibility are being made. What is more likely in the short term is that the U.S. military will use its forces to engage in sabotage and intimidation in hopes of reversing support for the nations aligned with ALBA. It is also very possible that the U.S. military will help to support proxy armies, such as Colombia's, in military conflicts that align with U.S. interests. However, this is a dangerous game. Even in the short term, the U.S. ruling class may drag the nation into another direct conflict, in spite of their intentions, that could spread to involve numerous other nations.
