U.S. Secretary of State Hillary Rodham Clinton called the WikiLeaks release of hundreds of thousands of classified diplomatic cables not just an attack on American interests, but damaging to the whole international community.
Secretary Clinton reiterated earlier promises by others in the Obama administration that the U.S. was taking "aggressive steps" to hold the leakers responsible.
"(The release) puts people's lives in danger, threatens national security and undermines efforts to work with other countries to solve shared problems," said Sec. Clinton, adding that she feels deep "regret" at the release of confidentional information. "There is nothing laudable about endangering innocent people, nothing brave about sabotaging the peaceful relations between nations."
Amid the diplomatic scrambling Sec. Clinton admitted was taking place, she expressed optimism about American diplomacy's ability to withstand any fallout from the leaks.
"I am confident that the partnerships and relationships that we have built will withstand this challenge," Sec. Clinton said. "The relationships are the centerpiece of our foreign policy. (One foreign counterpart said to me), 'You know, don't worry about it. You should see what we say about you.'"
Clinton may have to confront the release's fallout first hand after she leaves Washington on a four-nation tour of Central Asia and the Middle East - a region that figures prominently in the leaked documents.
At Clinton's first stop in Astana, Kazakhstan, she will be attending a summit of officials from the Organization for Security and Cooperation in Europe, a diplomatic grouping that includes many officials from countries cited in the leaked cables.
Most of the disclosures focused on familiar diplomatic issues that have long stymied U.S. officials and their foreign counterparts - the nuclear ambitions of Iran, North Korea and Pakistan, China's growth as a superpower, the frustrations of combating terrorism.
But their publication could become problems for the officials concerned and for any secret initiatives they had preferred to keep quiet. The massive release of material intended for diplomatic eyes was quickly ruffling feathers in foreign capitals despite efforts by U.S. diplomats in recent days to shore up relations with key allies in advance of the leaks.
"Every country must be able to have candid conversations about the people and nations with which they deal," said Sec. Clinton, adding that there is a real "need for honest, private dialogue."
In London, Steve Field, a spokesman for British Prime Minister David Cameron, said "it's important that governments are able to operate on the basis of confidentiality of information." French Foreign Ministry spokesman Bernard Valero said "we strongly deplore the deliberate and irresponsible release of American diplomatic correspondence by the site Wikileaks."
Pakistan's foreign ministry said it was an "irresponsible disclosure of sensitive official documents" while Iraq's foreign minister, Hoshyar Zebari, called the document release "unhelpful and untimely." In Australia, Assange's home country, Attorney General Robert McClelland said law enforcement officials were investigating whether WikiLeaks broke any laws.
Earlier Monday, Attorney General Eric Holder told reporters at the Justice Department that the administration would prosecute if violations of federal law are found in a criminal investigation of the incident.
The weekend release of documents reflecting, in some cases, unflattering assessments of world leaders has caused embarrassment to the administration. The director of the White House's Office of Management and Budget, Jacob Lew, said in ordering the agency-wide assessment Monday that the disclosures are unacceptable and will not be tolerated.
"Any unauthorized disclosure of classified information is a violation of our law and compromises our national security," Lew said in a memo obtained by The Associated Press.
The U.S. cables contained raw comments normally muffled by diplomatic politesse: Saudi Arabia's King Abdullah pressing the U.S. to "cut off the head of the snake" by taking action against Iran's nuclear program. Italian Prime Minister Silvio Berlusconi described as "feckless" and "vain." German Chancellor Angela Merkel dismissed as "risk averse and rarely creative."
Publication of the secret memos and documents made public by the online whistle-blower Wikileaks Sunday amplified widespread global alarm about Iran's nuclear ambitions. It also unveiled occasional U.S. pressure tactics aimed at hot spots in Afghanistan, Pakistan and North Korea. The leaks disclosed bluntly candid impressions from both diplomats and other world leaders about America's allies and foes.
It was, said Italian Foreign Minister Franco Frattini, the "Sept. 11 of world diplomacy."

In Washington, Rep. Peter Hoekstra of Michigan, the senior Republican on the House Intelligence Committee, called the release very damaging.
"The catastrophic issue here is just a breakdown in trust," he said Monday on CBS' "The Early Show", adding that many other countries - allies and foes alike - are likely to ask, 'Can the United States be trusted? Can the United States keep a secret?' "
The encrypted e-mails and other documents unearthed new revelations about long-simmering nuclear trouble spots, detailing U.S., Israeli and Arab world fears of Iran's growing nuclear program, American concerns about Pakistan's atomic arsenal and U.S. discussions about a united Korean peninsula as a long-term solution to North Korean aggression.
The documents published by The New York Times, France's Le Monde newspaper, Britain's Guardian newspaper, German magazine Der Spiegel and Spain's El Pais newspaper, laid out the behind-the-scenes conduct of Washington's international relations, shrouded in public by platitudes, smiles and handshakes at photo sessions among senior officials.
The WikiLeaks release "has the potential to change the course of diplomacy forever in the age of the Internet," says CBS News foreign affairs analyst Pamela Falk, based at U.N. Headquarters.
The White House immediately of the WikiLeaks documents, saying "such disclosures put at risk our diplomats, intelligence professionals and people around the world who come to the United States for assistance in promoting democracy and open government."
U.S. officials may also have to mend fences after revelations that they gathered personal information on other diplomats. The leaks cited American memos encouraging U.S. diplomats at the United Nations to collect detailed data about the U.N. secretary general, his team and foreign diplomats - going beyond what is considered the normal run of information-gathering expected in diplomatic circles.
State Department spokesman P.J. Crowley played down the diplomatic spying allegations. "Our diplomats are just that, diplomats," he said. "They collect information that shapes our policies and actions. This is what diplomats, from our country and other countries, have done for hundreds of years."
The White House noted that "by its very nature, field reporting to Washington is candid and often incomplete information. It is not an expression of policy, nor does it always shape final policy decisions."
"Nevertheless, these cables could compromise private discussions with foreign governments and opposition leaders, and when the substance of private conversations is printed on the front pages of newspapers across the world, it can deeply impact not only U.S. foreign policy interests, but those of our allies and friends around the world," the White House said.

On its website, The New York Times said "the documents serve an important public interest, illuminating the goals, successes, compromises and frustrations of American diplomacy in a way that other accounts cannot match."
Le Monde said it "considered that it was part of its mission to learn about these documents, to make a journalistic analysis and to make them available to its readers." Der Spiegel said that in publishing the documents its reporters and editors "weighed the public interest against the justified interest of countries in security and confidentiality."
WikiLeaks founder Julian Assange claimed the administration was trying to cover up alleged evidence of serious "human rights abuse and other criminal behavior" by the U.S. government. WikiLeaks posted the documents just hours after it claimed its website had been hit by a cyberattack that made the site inaccessible for much of the day.
But extracts of the more than 250,000 documents posted online by news outlets that had been given advance copies of the documents showed deep U.S. concerns about Iranian and North Korean nuclear programs along with fears about regime collapse in Pyongyang.
The Guardian said some cables showed King Abdullah of Saudi Arabia repeatedly urging the United States to attack Iran to destroy its nuclear program. The newspaper also said officials in Jordan and Bahrain have openly called for Iran's nuclear program to be stopped by any means and that leaders of Saudi Arabia, the United Arab Emirates and Egypt referred to Iran "as 'evil,' an 'existential threat' and a power that 'is going to take us to war,"' The Guardian said.
Those documents may prove the trickiest because even though the concerns of the Gulf Arab states are known, their leaders rarely offer such stark appraisals in public.
"The fact that these governments are exhorting and pushing the U.S. government to be more aggressive, to take military action - those revelations will not be popular in the streets of those countries in the Arab world," said CBS News national security consultant Juan Zarate.
The cables also make it clear, reports CBS News correspondent David Martin, that Iran has found ways to beat U.S. and United Nations sanctions aimed at pressuring the nation into halting uranium enrichment. U.S. intelligence agents warned, for instance, that Iran was getting advanced missiles from North Korea that could strike European capitals.
The Times highlighted documents that indicated the U.S. and South Korea were "gaming out an eventual collapse of North Korea" and discussing the prospects for a unified country if the isolated, communist North's economic troubles and political transition lead it to implode.
The Times also cited diplomatic messages describing unsuccessful U.S. efforts to prod Pakistani officials to remove highly enriched uranium from a reactor out of fear that the material could be used to make an illicit atomic device. And the newspaper cited exchanges showing Yemen's president, Ali Abdullah Saleh, telling Gen. David Petraeus that his country would pretend that American missile strikes against a local al Qaeda group had come from Yemen's forces.
The paper also cited documents showing the U.S. used hardline tactics to win approval from countries to accept freed detainees from Guantanamo Bay. It said Slovenia was told to take a prisoner if its president wanted to meet with President Barack Obama and said the Pacific island of Kiribati was offered millions of dollars to take in a group of detainees.
It also cited a message from the U.S. Embassy in Beijing that included allegations from a Chinese contact that China's Politburo directed a cyber intrusion into Google's computer systems as part of a "coordinated campaign of computer sabotage carried out by government operatives, private security experts and Internet outlaws."
Le Monde said another memo asked U.S. diplomats to collect basic contact information about U.N. officials that included Internet passwords, credit card numbers and frequent flyer numbers. They were asked to obtain fingerprints, ID photos, DNA and iris scans of people of interest to the United States, Le Monde said.
The Times said another batch of documents raised questions about Italian Prime Minister Silvio Berlusconi and his relationship with Russian Prime Minister Vladimir Putin. One cable said Berlusconi "appears increasingly to be the mouthpiece of Putin" in Europe, the Times reported.
Der Spiegel reported that the documents portrayed German Chancellor Angela Merkel and Foreign Minister Guido Westerwelle in unflattering terms. It said American diplomats saw Merkel as risk-averse and Westerwelle as largely powerless.
Libyan leader Moammar Gadhafi, meanwhile, was described as erratic and in the near constant company of a Ukrainian nurse who was described in one cable as "a voluptuous blonde," according to the Times.
The State Department's top lawyer warned Assange late Saturday that lives and military operations would be put at risk if the cables were released. Legal adviser Harold Koh said WikiLeaks would be breaking the law if it went ahead. He also rejected a request from Assange to cooperate in removing sensitive details from the documents.
