Venezuelan President Hugo Chavez’s gift of a book may not have won President Obama over. So how about an island? The Venezuelan government has formally donated Petty Island back to the United States. The US may not be won over, however, since it probably considers the island rightfully its own: It’s located in the Delaware River, near Philadelphia. Venezuela’s state-run energy company, PDVS, bought the island in 1990. It has used the island for fuel storage and refinement since 1990.
