WASHINGTON - The Republican speaker of the US House of Representatives added to his party's criticism of the Iran nuclear deal on Tuesday with a harsh statement saying the agreement likely will fuel an international nuclear arms race."Instead of stopping the spread of nuclear weapons in the Middle East, this deal is likely to fuel a nuclear arms race around the world," Boehner said in a statement.He said President Barack Obama, a Democrat, abandoned his own goals for a deal in the course of the negotiations.
