Tensions between the United States and Venezuelan governments are flaring one week after the death of Venezuelan President Hugo Chávez. The Obama administration has expelled two Venezuelan diplomats, an apparent retaliation for Venezuela’s expulsion of two U.S. military attachés last week. The attachés were accused of planning to destabilize Venezuela. On Tuesday, Venezuelan Foreign Minister Elías Jaua renewed the claim, accusing the United States of plotting to topple Chávez before his death.
