U.S. Military Controversy
In 2006, a classified memo was leaked that revealed the United States has interest in an air base in Mariscal Estigarribia, Paraguay. This memo, authored by David Wurmser and Michael Maloof, [1] notes that both Wurmser, and Maloof had met the American neo-conservatives to discuss a plan to attack "terrorists" in the natural reserve rich South American region. About 500 US troops landed in at the air base in Mariscal Estigarribia, Paraguay in July 2005, after Paragua's senate voted to authorize immunity from the International Criminal Court. American occupation of this base would put the Bolivian gas fields at center stage of the region.
