Job Indonesia - The founder of Wikileaks, Julian Assange, said the US authorities were afraid of being held to account.
But the White House said the release was "reckless" put the lives of diplomats and others at risk.
One Republican congressman called for Wikileaks to be designated a terrorist organisation.
Peter King, a member of the House of Representatives Homeland Security Committee, said the latest release "manifests Mr Assange's purposeful intent to damage not only our national interests in fighting the war on terror, but also undermines the very safety of coalition forces in Iraq and Afghanistan".
The US Department of Defence says it is making its computer systems more secure to prevent future leaks.
Computer hacking
Wikileaks has only posted some 200 of the 251,287 messages it says it has obtained. However, the entire bundle of cables has been made available to five publications, including the New York Times and the UK's Guardian newspaper.

Shedding light on wars?
Wikileaks argues that the site's previous releases shed light on the wars in Afghanistan and Iraq. The leaked embassy cables are both contemporary and historical, and include a 1989 note from a US diplomat in Panama City musing about the options open to Panamanian leader Manuel Noriega and referring to him as "a master of survival" - the author apparently had no idea that US forces would invade a week later and arrest Noriega.
In a statement, the White House said: "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.
"President Obama supports responsible, accountable, and open government at home and around the world, but this reckless and dangerous action runs counter to that goal."
No-one has been charged with passing the diplomatic files to the website but suspicion has fallen on US Army private Bradley Manning, an intelligence analyst arrested in Iraq in June and charged over an earlier leak of classified US documents to Mr Assange's organisation.
The cables release was the third mass Wikileaks release of classified documents since it published 77,000 secret US files on the Afghan conflict in July, and 400,000 documents about the Iraq war in October.
Wikileaks argues the release of the documents has shed light on the wars, including allegations of torture and reports that suggest 15,000 additional civilian deaths in Iraq.
