Bargaining to empty the Guantánamo Bay prison: When American diplomats pressed other countries to resettle detainees, they became reluctant players in a State Department version of “Let’s Make a Deal.” Slovenia was told to take a prisoner if it wanted to meet with President Obama, while the island nation of Kiribati was offered incentives worth millions of dollars to take in Chinese Muslim detainees, cables from diplomats recounted. The Americans, meanwhile, suggested that accepting more prisoners would be “a low-cost way for Belgium to attain prominence in Europe.”

...Clashes with Europe over human rights: American officials sharply warned Germany in 2007 not to enforce arrest warrants for Central Intelligence Agency officers involved in a bungled operation in which an innocent German citizen with the same name as a suspected militant was mistakenly kidnapped and held for months in Afghanistan. A senior American diplomat told a German official “that our intention was not to threaten Germany, but rather to urge that the German government weigh carefully at every step of the way the implications for relations with the U.S.”

On Yemen:

For instance, it has been previously reported that the Yemeni government has sought to cover up the American role in missile strikes against the local branch of Al Qaeda. But a cable’s fly-on-the-wall account of a January meeting between the Yemeni president, Ali Abdullah Saleh, and Gen. David H. Petraeus, then the American commander in the Middle East, is nonetheless breathtaking.

“We’ll continue saying the bombs are ours, not yours,” Mr. Saleh said, according to the cable sent by the American ambassador, prompting Yemen’s deputy prime minister to “joke that he had just ‘lied’ by telling Parliament” that Yemeni forces had carried out the strikes.

The Guardian calls the release a "global diplomatic crisis" " and says Hillary Clinton is in charge of damage control.

And, if there was any lingering doubt the U.S. has become Spy Central, there shouldn't be.

The cables published today reveal how the US uses its embassies as part of a global espionage network, with diplomats tasked to obtain not just information from the people they meet, but personal details, such as frequent flyer numbers, credit card details and even DNA material.

Classified "human intelligence directives" issued in the name of Hillary Clinton or her predecessor, Condoleeza Rice, instruct officials to gather information on military installations, weapons markings, vehicle details of political leaders as well as iris scans, fingerprints and DNA.

The most controversial target was the leadership of the United Nations. That directive requested the specification of telecoms and IT systems used by top UN officials and their staff and details of "private VIP networks used for official communication, to include upgrades, security measures, passwords, personal encryption keys".

Who has the Wikileaks documents? The New York Times, the Guardian, Der Spiegel in Germany, Le Monde in France and El País in Spain.

All five plan to publish extracts from the most significant cables, but have decided neither to "dump" the entire dataset into the public domain, nor to publish names that would endanger innocent individuals. WikiLeaks says that, contrary to the state department's fears, it also initially intends to post only limited cable extracts, and to redact identities.
