Wikileaks has unravelled some of the documents which reveal the truth behind inaction than action by the United States in Afghanistan in the last one decade.

It was long wished that the U.S. army would one day nail down the most wanted terrorist Osama bin-Laden and bring him to Guantanamo Bay detention center. But the latest string of leaks reveal that al Qaeda had warned to set off a “nuclear hellstorm” if Osama bin Laden is ever captured or killed.

This explains the rationale behind inaction than action in Afghanistan. Wikileaks' files show that al Qaeda's senior leader Khalid Sheikh Mohammed, who was detained and interrogated, had spilled the beans that the terrorist group had, indeed, hidden a nuclear bomb in Europe and that it would be detonated if Osama bin Laden is captured or killed.

Khalid Sheikh Mohammed was one of the self-confessed terrorist who had planned the 9/11 terrorist attacks in the United States that killed more than 3,000 people.

The secret files show the interrogation details of more than 750 Guantanamo Bay detainees. Another revelation from the files was that Al-Qaeda planned chemical and biological attacks in London and also had a sketch on how to put cyanide in air-conditioning units of some public offices in the US.

These documents also show that the key al-Qaeda leaders were in a house in Karachi, Pakistan, on Sept. 11, 2001 watching live the attacks on New York and Pentagon.
