WASHINGTON - Iran could produce enough weapon-grade uranium for one or more nuclear bombs by mid-2014, and the United States and its allies should intensify sanctions on Tehran before that point is reached, a report by a group of US nonproliferation experts said.
President Barack Obama should also clearly state that the United States will take military action to prevent Iran from acquiring a nuclear weapon, the report said.
The UN nuclear watchdog, the International Atomic Energy Agency, has expressed concern that Iran's nuclear program has a military dimension. Tehran, which says its nuclear program is for peaceful energy purposes, calls those allegations baseless.
The 154-page report, "US Nonproliferation Strategy for the Changing Middle East," produced by five nonproliferation experts, was expected to be released on Monday.
"Based on the current trajectory of Iran's nuclear program, we estimate that Iran could reach critical capability in mid-2014," the report said.
