No wonder why terrorists attacks happen in Pakistan, you created the fire:
On a cold and blustery evening in December 1989, Huthaifa Azzam, the teenage son of the legendary Jordanian-Palestinian mujahideen leader Sheikh Abdullah Azzam, went to the airport in Peshawar, Pakistan, to welcome a group of young men. All were new recruits, largely from Jordan, and they had come to fight in a fratricidal civil war in neighboring Afghanistan—an outgrowth of the CIA-financed jihad of the 1980s against the Soviet occupation there.
The men were scruffy, Huthaifa mused as he greeted them, and seemed hardly in battle-ready form. Some had just been released from prison; others were professors and sheikhs. None of them would prove worth remembering—except for a relatively short, squat man named Ahmad Fadhil Nazzal al-Khalaylah.
He would later rename himself Abu Musab al-Zarqawi.
he allegedly carried out a car-bomb attack at the Jordanian embassy in Baghdad. Twelve days later, he was linked to the bombing of the United Nations headquarters, in which twenty-two people died. And on August 29, in what was then the deadliest attack of the war, he engineered the killing of over a hundred people, including a revered cleric, the Ayatollah Muhammad Baqr al-Hakim, in a car bombing outside Shia Islam’s holy shrine in Najaf. The suicide bomber in that attack was Yassin Jarad, from Zarqa. He was al-Zarqawi’s father-in-law.
Under al-Zarqawi, al Qaeda in Iraq tries to spark a sectarian war against the majority Shia community. Al-Zarqawi is killed in a US strike in 2006 . Abu Ayyub al-Masri takes his place as leader of AQI. Al-Masri announces the creation of Islamic State of Iraq (ISI), and establishes Abu Omar al-Baghdadi as its leader in 2006, April 2010 - Abu Bakr al-Baghdadi becomes leader of ISI after Abu Omar al-Baghdadi and al-Masri are killed in a joint US-Iraqi operation.
In April 2013 - ISI declares its absorption of an al Qaeda-backed militant group in Syria, Jabhat al-Nusra, also known as the al-Nusra Front. Al-Baghdadi says that his group will now be known as Islamic State in Iraq and the Levant (ISIL or ISIS).
