Coca production on their land is there because they have no alternative means of subsistence. This means that whatever land is not in the way of the megaprojects will be turned into centrally managed plantations stripping the people of their autonomy in order to be made into laborers. The black communities recognize this as a violation of their freedom. In this time of capitalist globalization they only see their struggle as successful if other struggles for freedom also succeed. For the same reason that the FTAA is about all of the Americas, the effects of Plan Colombia are not to remain within the Colombian borders.
Social movements are on the rise in all of Colombia's neighboring countries.
And Venezuela, with even larger oil fields than Colombia, is becoming a place of concern to western capitalists ever since president Chavez was known to be negotiating with Cuba, Iraq and other non-western oil producers. Thus it is in the interest of the western oil producers that the US have a strong military pesence in South America. Thus, one of the tasks of Plan Colombia is to build bases in surrounding countries. In Panama, for example, near the Colombian border, live peacefully the indigenous Kuna people. Now, they are fighting against American intentions of creating a naval base on their land, while they are intimidated with the increased presence of US soldiers.
