The United States  was catapulted into a worldwide diplomatic crisis today, with the  leaking to the Guardian and other international media of more than  250,000 classified cables from its embassies, many sent as recently as  February this year.
At the start of a series of daily extracts from the US embassy cables  – many designated "secret" – the Guardian can disclose that Arab  leaders are privately urging an air strike on Iran and that US officials  have been instructed to spy on the UN  leadership.
These two revelations alone would be likely to reverberate around the world. But the secret dispatches, which were obtained by WikiLeaks, the whistleblowers' website, also reveal Washington's evaluation of many other highly sensitive international issues.
These  include a shift in relations between China and North Korea, high-level  concerns over Pakistan's growing instability, and details of clandestine  US efforts to combat al-Qaida in Yemen.
Among scores of disclosures that are likely to cause uproar, the cables detail:
•  Grave fears in Washington and London over the security of Pakistan's  nuclear weapons programme, with officials warning that as the country  faces economic collapse, government employees could smuggle out enough  nuclear material for terrorists to build a bomb.
• Inappropriate remarks by Prince Andrew about a UK law enforcement agency and a foreign country.
•  Suspicions of corruption in the Afghan government, with one cable  alleging that vice-president Zia Massoud was carrying $52m in cash when  he was stopped during a visit to the United Arab Emirates. Massoud  denies taking money out of Afghanistan.
• How the hacker attacks  which forced Google to quit China in January were orchestrated by a  senior member of the Politburo who typed his own name into the global  version of the search engine and found articles criticising him  personally.
• Allegations that Russia and its intelligence  agencies are using mafia bosses to carry out criminal operations, with  one cable reporting that the relationship is so close that the country  has become a "virtual mafia state".
• The extraordinarily close  relationship between Vladimir Putin, the Russian prime minister, and  Silvio Berlusconi, the Italian prime minister, which is causing intense  US suspicion. Cables detail allegations of "lavish gifts", lucrative  energy contracts and the use by Berlusconi of a "shadowy"  Russian-speaking Italiango-between.
• Devastating criticism of the  UK's military operations in Afghanistan by US commanders, the Afghan  president and local officials in Helmand. The dispatches reveal  particular contempt for the failure to impose security around Sangin –  the town which has claimed more British lives than any other in the  country.
The US has particularly intimate dealings with Britain,  and some of the dispatches from the London embassy in Grosvenor Square  will make uncomfortable reading in Whitehall and Westminster. They range  from political criticisms of David Cameron to requests for specific  intelligence about individual MPs.
The cables contain specific  allegations of corruption, as well as  harsh criticism by US embassy  staff of their host governments, from Caribbean islands to China and  Russia. The material includes a reference to Putin as an "alpha-dog" and  Hamid Karzai as being "driven by paranoia", while Angela Merkel  allegedly "avoids risk and is rarely creative". There is also a  comparison between Mahmoud Ahmadinejad and Adolf Hitler.
