trib.al – CARACAS, Venezuela — Six months ago, Venezuelan President Nicolás Maduro faced bloody protests demanding his resignation. The streets were clogged with flaming barricades. By the time the smoke cleared, dozens of protesters and national guardsmen were dead, and Maduro’s government was widely assailed for rights abuses. Those were the good old days. Venezuelan oil, the lifeblood of the leftist revolution entrusted to Maduro by the late Hugo Chávez, was worth $97 a barrel then.
