It is clear that to the West, as they were during the proxy war against the Soviets, and during attempts to forge an oil pipeline across Afghan territory, the Taliban remain a tool, not an ally - to be used and abused whenever and however necessary to advance Wall Street and Washington's agenda - a self-serving Machiavellian agenda clearly devoid of principles.It's clear from this and many other articles that the Empire of Chaos, as Pepe Escobar likes to refer to the US Empire, sponsors terrorist groups to serve their imperialist agendas. We've seen this in El Salvador, Nicaragua, Iraq, Chechnya, Syria to name a few countries, and we've seen widespread evidence of government agency involvement with domestic terrorist incidents (Oklahoma City Bombing, 9/11, Boston Bombing, several "terrorist" incidents organized by the FBI through entrapment) in the US to justify the construction of a police state that for now stays somewhat hidden behind a veneer of rule of law.
This can be seen in play, even now as the Taliban serve as a proxy force to torment the West's political enemies in Pakistan with and serve as a perpetual justification for military intervention in neighboring Afghanistan.
Basically terrorism sows fear among the targeted population which can further the imperialist agenda abroad and the containment of political opposition here at home.
