Paraguay

2000 August: "After weathering one of the most half-hearted coup attempts in Latin America, Paraguay’s President Luis González Macchi declared a state of emergency, granting himself broad powers to rule by decree." [1]
2005 May: the nation’s Congress was convened in secret, after midnight, according to a May 31 report by the Argentine correspondent for the Mexican daily La Jornada. The reason: to rush through a law “that will permit United States troops to enter this South American country for 18 months, with immunity for all personnel that participate in activities of training and advising, including civilian personnel.” [2] [3]
