The WikiLeaks diplomatic cables release of November-December 2010 was the largest coordinated leak of classified government documents in history to that point — a quarter-million cables spanning decades of American diplomatic correspondence, released in partnership with major newspapers including The Guardian, Der Spiegel, Le Monde, El País, and The New York Times.

For readers overwhelmed by the volume, here was what actually mattered:

On the Middle East: Arab governments, particularly Saudi Arabia, had been privately urging the United States to attack Iran's nuclear program — in stark contrast to their public postures. King Abdullah of Saudi Arabia had reportedly told American officials to "cut off the head of the snake."

On Pakistan: American diplomats expressed deep private skepticism about Pakistani intelligence's relationship with militant groups, even as billions in aid flowed to Islamabad. The cables showed a US-Pakistan relationship built substantially on mutual pretense.

On Afghanistan: The corruption of the Karzai government was documented in clinical detail by American diplomats who simultaneously publicly praised it.

On China: Internal debates about North Korean succession and China's ambivalence about the Kim regime were revealed, complicating Beijing's public positions.

On Italy: Cables described Prime Minister Berlusconi as "feckless, vain, and ineffective" — candid assessments that caused diplomatic frictions when published.

The broader significance: WikiLeaks demonstrated that the private face of American foreign policy often contradicted the public one in systematic ways — not as isolated hypocrisy but as a feature of how great powers operate. The world had known this abstractly; the cables made it concrete.
