This was a very interesting article; thank you for posting it.
What do you think will happen now?
I see the future of a front-line drug interdiction base very bleak.
Colombia is surrounded by countries either hostile to the US or, at the very least, not receptive of allowing US troops in their territories.
And as the article says, placing US troops in Colombia herself would be a dumb idea.
I think the US would have to make do with all-electronic, all-satellite surveillance, but with drug traffic from South America now quite low in the US national security totem pole, I think source interdiction will be benignly neglected.
This is a consequence of 9/11, remarked by US allies in the region: Latin America and the drug trade took a WAY back seat to the Middle East and Islamic extremist terrorism.
