As the US prepares to leave Afghanistan, Pakistani spy agency ISI is engaged in helping Taliban - a terrorist outfit which the intelligence agency has been helping for more than two decades now, a top American expert on South Asian affairs has said.
"For twenty years Pakistan's army - the real power broker in the country - has backed the Afghan Taliban. It helped create the Taliban's Islamic Emirate in the 1990s and build the al-Qaeda state within a state," Bruce Riedel, former CIA official and now a scholar at the Brookings Institute, said.
