September 15, 2005 Estigarribia Military Base in Paraguay, © ClarinControversy is raging in Paraguay, where the U.S. military is conducting secretive operations. 500 U.S. troops arrived in the country on July 1st with planes, weapons and ammunition. Eyewitness reports prove that an airbase exists in Mariscal Estigarribia, Paraguay, which is 200 kilometers from the border with Bolivia and may be utilized by the U.S. military. Officials in Paraguay claim the military operations are routine humanitarian efforts and deny that any plans are underway for a U.S. base. Yet human rights groups in the area are deeply worried. White House officials are using rhetoric about terrorist threats in the tri-border region (where Paraguay, Brazil and Argentina meet) in order to build their case for military operations, in many ways reminiscent to the build up to the invasion of Iraq.
