Pakistan has long been accused by its neighbours India and Afghanistan, and western nations like the United States and the United Kingdom of its involvement in terrorist activities in the region and beyond. Pakistan's tribal region along its border with Afghanistan has been claimed to be a "haven for terrorists" by western media and the United States Defense Secretary.According to an analysis published by the Saban Center for Middle East Policy at Brookings Institution in 2008, Pakistan was, "with the possible exception of Iran, perhaps the world’s most active sponsor of terrorist groups... aiding groups that pose a direct threat to the United States." Daniel Byman, an author, also wrote that, "Pakistan is probably 2008's most active sponsor of terrorism"
Allegations of state-sponsored terrorism :
Author Gordon Thomas states that whilst aiding in the capture of Al Qaeda members, Pakistan "still sponsored terrorist groups in the Indian state of Jammu and Kashmir, funding, training and arming them in their war of attrition against India". Journalist Stephen Schwartz notes that several terrorist and criminal groups are "backed by senior officers in the Pakistani army, the country's ISI intelligence establishment and other armed bodies of the state". According to Ted Galen Carpenter, a senior fellow for defense and foreign policy studies at the Cato Institute, "Without the active support of the government in Islamabad, it is doubtful whether the Taliban could ever have come to power in Afghanistan. Pakistani authorities helped fund the militia and equip it with military hardware during the mid-1990s when the Taliban was merely one of several competing factions in Afghanistan’s civil war. Only when the United States exerted enormous diplomatic pressure after the Sept. 11 attacks did Islamabad begin to sever its political and financial ties with the Taliban. Even now it is not certain that key members of Pakistan’s intelligence service have repudiated their Taliban clients.
Afghanistan is not the only place where Pakistani leaders have flirted with terrorist clients. Pakistan has also assisted rebel forces in Kashmir even though those groups have committed terrorist acts against civilians. And it should be noted that a disproportionate number of the extremist madrasas schools funded by the Saudis operate in Pakistan."Pakistan's former ambassador to the U.S., Husain Haqqani has said Pakistan sponsors terrorism.
According to author Daniel Byman, "Pakistan is probably today's most active sponsor of terrorism." Writing in an article published by The Australian he stated, "following the terror massacres in Mumbai, Pakistan may now be the single biggest state sponsor of terrorism, beyond even Iran, yet it has never been listed by the US State Department as a state sponsor of terrorism".
Former Pakistani president Pervez Musharraf has conceded that his forces trained militant groups to fight India in Indian-administered Kashmir. He confessed that the government ″turned a blind eye″ because it wanted to force India to enter into negotiations, as well as raise the issue internationally. He also said Pakistani spies in the Inter-Services Intelligence directorate (ISI) cultivated the Taliban after 2001 because Karzai's government was dominated by non-Pashtuns, who are the country's largest ethnic group, and by officials who were thought to favour India.
India has been consistent in alleging that Pakistan was involved in training and arming underground militant groups to fight Indian forces in Kashmir.
Notorious Inter-Services Intelligence and terrorism :
The ISI, has often been accused of playing a role in major terrorist attacks across India including terrorism in Kashmir, the July 2006 Mumbai Train Bombings, the 2001 Indian Parliament attack, the 2006 Varanasi bombings, the August 2007 Hyderabad bombings, and the November 2008 Mumbai attacks.
The ISI is also accused of supporting Taliban forces and recruiting and training mujahideen to fight in Afghanistan and Kashmir. Based on communication intercepts, US intelligence agencies concluded Pakistan's ISI was behind the attack on the Indian embassy in Kabul on 7 July 2008, a charge that the governments of India and Afghanistan had laid previously.
The Pakistani intelligence agency, the ISI, is believed to be aiding these organisations in eradicating perceived enemies or those opposed to their cause, including India, Russia, China, Israel, the United States, the United Kingdom and other members of NATO. Satellite imagery from the FBI suggest the existence of several terrorist camps in Pakistan, with at least one militant admitting to being trained in the country as part of the going Kashmir Dispute, Pakistan is alleged to be supporting separatist militias Many nonpartisan sources believe that officials within Pakistan's military and the Inter-Services Intelligence (ISI) sympathise with and aid Islamic terrorists, saying that the "ISI has provided covert but well-documented support to terrorist groups active in Kashmir, including the al-Qaeda affiliate Jaish-e-Mohammed".
President of Afghanistan Hamid Karzai has regularly reiterated allegations that militants operating training camps in Pakistan have used it as a launch platform to attack targets in Afghanistan. He has also urged Western military allies to target extremist hideouts in neighbouring Pakistan. In response to the millants from Afghanistan hiding in the mountainous tribal region of Pakistan . The US and Pakistan agreed to allow US Drone Strikes in Pakistan.
Several detainees at the Guantanamo Bay facility told US interrogators that they were aided by the ISI for attacks in the disputed Kashmir Region.
