http://www.nytimes.com/2004/08/09/politics/09nuke.html?ex=1092715200&en=c95ce6f723d4a86c&ei=5006&partner=ALTAVISTA1KENNEBUNKPORT, Me., Aug. 8 - President Bush's national security adviser said Sunday that the United States and its allies "cannot allow the Iranians to develop a nuclear weapon" and warned that President Bush would "look at all the tools that are available to him" to stop Iran's program.
Condoleezza Rice, the national security adviser, said on the NBC News program "Meet the Press" that she expected that the International Atomic Energy Agency would make what she called "a very strong statement" in September forcing Iran to choose between isolation or the abandonment of its nuclear weapons efforts. But she stopped short of saying whether the United States could muster its allies to impose sanctions against Iran in the United Nations Security Council.
Until now, European powers and Russia have resisted American efforts to impose sanctions against Iran, which they see as a major trading partner.
Iran has insisted that its nuclear effort is entirely for the production of electric power, though the International Atomic Energy Agency, the United Nations' nuclear monitoring agency, has found evidence of covert efforts, stretching back more than 18 years, to produce highly enriched uranium suitable primarily for weapons production.
A week ago, Iran's foreign minister, Kamal Kharrazi, said his country would resume producing parts for centrifuges, the equipment needed to enrich uranium, because European nations had not brought the Atomic Energy Agency's investigations to a close.
President Bush, who took a brief break from his re-election campaign to attend a family wedding here and visit his parents, said nothing in public on Sunday. He attended an early-morning church service, went fishing with members of his family and flew back to Washington, letting his aides take the questions about Iraq, terrorism, Iran and North Korea.
Ms. Rice was responding to an article in The New York Times on Sunday that said the Bush administration's flurry of diplomatic efforts during the past 20 months to stop the progress of nuclear weapons programs in Iran and North Korea had so far failed.
In a veiled reference to the Clinton administration, Ms. Rice said "these are problems that developed in 1990's." She contended that there had been "diplomatic successes" in organizing North Korea's neighbors to confront the problem and spurring action against Iran at the Vienna-based Atomic Energy Agency.
"It was, in fact, the president who really put this on the agenda in his State of the Union address, the famous 'axis of evil' address," Ms. Rice said. "And our allies have really begun to respond."
She declined to say whether the United States would support action by Israel, which says Iran's program poses a particular threat to its national security, to attack Iran's facilities the way it attacked the Osirak reactor in Iraq in 1981.
"I think that I don't want to get into hypotheticals on this," Ms. Rice said. "I do think that there are very active efforts under way, for instance, to undermine the ability of the Iranians under the cover of civilian nuclear cooperation to get the components that would help them for nuclear weapons developments."
She said Russia had declared that it would provide help to Iran only if it returned its nuclear fuel to Russia so it could not be diverted for weapons. "I think you cannot allow the Iranians to develop a nuclear weapon," she said. "The international community has got to find a way to come together and to make certain that that does not happen."
Ms. Rice's answer about Israel was particularly notable because, in the period before the war in Iraq, she and other senior administration officials said history had vindicated the Israeli raid on Osirak. Had that attack not crippled Iraq's main nuclear reactor, they argued, Saddam Hussein might have had access to nuclear weapons before the Persian Gulf war in 1991.
But it is unclear that Israel has the military capacity to reach Iran's nuclear sites, which are much farther away and well hidden among cities.
