What was on effect of al-qaeda’s september 11, 2001, attack on the world trade center in new york and the pentagon in virginia?

The main effect after the attacks of September 11, perpetrated by the terrorist organization Al Qaeda, was the start of the War on Terror and the Bush Doctrine of preventive attack. As a result of these changes, less than a month later the Afghanistan War began, because this country was governed by the Taliban that provided refuge to many of the high command of al Qaeda, including Osama Bin Laden, who as a consequence from the invasion he had to escape to the mountains of Pakistan. Then, in 2003, the War in Iraq followed the guidelines of the Bush Doctrine, due to suspicions that Saddam Hussein's authoritarian regime was developing weapons of mass destruction.
