Answer:
Answer 1: According to President Obama, Osama bin Laden had been plotting attacks against the US and its allies for over two decades.
Answer 2: Bin Laden's death is not the end of the War on Terror because terrorism is a complex problem that is often rooted in socio-economic, political, and religious grievances. In many cases, there are underlying causes of terrorism that cannot be simply eradicated with military force, meaning that it is an ongoing challenge for governments the world over. As such, the War on Terror is an ongoing battle of prevention, disruption, and disruption of terrorist activities, as well as addressing the root causes of terrorism that may lead to it in the first place.
