After nearly two months of paralysis, Bolivian President Rodrigo Paz signed a state-of-emergency decree in the early hours of Saturday, ordering police and soldiers onto the highways to break up the road blockades that have strangled the country since early May. The move came just hours after his government clinched a peace accord with the nation's largest labor confederation — but with the most aggressive blockading group flatly rejecting that deal and vowing to dig in, the decree lands on a country that is far from pacified.
