I am always repeating how Latin American countries rely too much on commodities, so I need to be fair. Chile, for example, does not only sell copper. It also might sell used European tanks to countries that, really, don't need them. Like Colombia, which is buying 60. Colombia needs plenty of tanks to fight a guerrilla war in the jungle as well as the phantom menace of Venezuela. Or maybe Colombia figures it can play with the tanks for a while, then still get some resale value by later selling them to an even poorer country that doesn't really need tanks.
