Iranian leaders must choose between cooperation with the West and confrontation, a State Department spokesman told reporters July 19 following a meeting between EU and Iranian diplomats on Iran's nuclear program, at which U.S. Undersecretary of State William Burns was in attendance. Burns reportedly did not meet separately with the Iranian delegation, the spokesman said, adding that EU foreign policy chief Javier Solana told Iran's representative that Iran must give a "clear answer" to the West within two weeks.
