so on tuesday the u.s. secretary of defense and chairman of the joint chiefs of staff will face questioning on capitol hill about the military withdrawal from afghanistan. now, since the u.s. exit, the country has seen a swift return to strict and brutal taliban law. a quick warning, the video you re about to see is graphic and may be difficult to watch. so over the weekend, militants put the dead bodies of alleged kidnappers on display in herat. the taliban are even cracking down on barbershops now, banning barbers from shaving men s beards or playing music in helmand province. joining me now is rohan, professor of security studiies n singapore and editor of afghanistan after the western drawdown. good to have you on the show, sir.
