President Bush would not rule out the use of nuclear force against Iran, according to this article:
President Bush refused on Tuesday to rule out nuclear strikes against Iran if diplomacy fails to curb the Islamic Republic’s atomic ambitions.
Iran, which says its nuclear program is purely peaceful, told world powers it would pursue atomic technology, whatever they decide at a meeting in Moscow later in the day.
Bush said in Washington he would discuss Iran’s nuclear activities with China’s President Hu Jintao this week and avoided ruling out nuclear retaliation if diplomatic efforts fail.
Asked if options included planning for a nuclear strike, Bush replied: “All options are on the table. We want to solve this issue diplomatically and we’re working hard to do so.”
