WikieLeaks documents show that the United States and Britian were alarmed over Al Qaeda getting nuclear material from Pakistan. There were concerns in both Washinton and London that Al Qaeda or its associates might get enough nuclear material from Pakistan's nuclear facilities to make a crude atom bomb. They were woried that the al Qaeda or its allies might try to get hold of nuclear material by attacking a nuclear facility or by staging ambush of nuclear transports or by infiltrating the country’s nuclear installations.The latest batch of classified US diplomatic cables published by the whistle-blowing website WikiLeaks also revealed growing concern among American and British diplomats over Pakistan building up its atomic weapons arsenal despite economic hardships and political instability.Excerpts of the cables were published by Der Spiegel, the Guardian of London, the New York Times, French newspaper Le Monde and Spanish daily El Pais.Last Sunday, Wikileaks began releasing a selection of over 250,000 classified US diplomatic cables. Even though there have been previous warnings about the possibility of nuclear material falling into the hands of terrorist groups in Pakistan, the latest Wikileaks revelations for the first time speak about a real danger of terrorist groups getting hold of nuclear material in spite of the Pakistani government's assurance that its nuclear sites are secure. Former US Ambassador to Pakistan Anne W Patterson, in a cable to the State Department on February 4, 2009, wrote that their major concern is not having an Islamic militant steal an entire weapon, but rather the chance someone working in Government of Pakistan facilities could gradually smuggle enough material out to eventually make a weapon. She was particularly worried about a stockpile of highly enriched uranium kept for years near an ageing research rector in Pakistan.The stockpile had enough uranium to build several 'dirty bombs. On May 27, 2009, she wrote to Washington saying that the Pakistan government was again refusing the US to remove the material as agreed two years before.The enriched uranium for the research reactor was supplied by the United States in the mid-1960s. Pakistan justified its refusal to return the fissile material saying that if the local media got word of the fuel removal, they certainly would portray it as the US taking Pakistan's nuclear weapons away.US diplomats in their correspondence expressed doubts whether the Pakistan government would end its support for the terrorists. Patterson said there is no chance that Pakistan will view enhanced assistance in any fields as sufficient compensation for abandoning support for these groups as it sees them as an important part of its national security apparatus against India. Britain's concern about Pakistan's nuclear material falling into the hands of terrorists were expressed by Mariot Leslie, Director General of Defence and Intelligence at the Foreign Office. She told US diplomats in September, 2009 that the UK has deep concerns about the safety and security of Pakistan’s nuclear weapons.The leaked diplomatic correspondence said US also voiced its concern about rapid expansion of Pakistan's nuclear weapons programme in an intelligence briefing in 2008. The Russian government shared the US and UK governments' concerns about Pakistan's nuclear programme.Russian foreign ministry official Yuri Korolev told US officials that, Islamists are not only seeking power in Pakistan, but they are also trying to get their hands on nuclear materials.Addressing a conference in Washington in February, he proposed that the problem of Pakistan's nuclear sites should be taken up in the on-going missile control talks.Over one Lakh 20 thousand people directly involved in Pakistan’s nuclear and missile programmes. He said there is no way to guarantee that all are 100 per cent loyal and reliable.
