Iran do have links with Taliban, Mullah Mansoor was droned when he was coming from Iran if you remember.
My issue is with my own. There are individuals here on this vary forum, who are staunch opponents of Talibans, without menacing words, due to sectarian affiliations. How do they see now this Iranian support of Taliban, has this all of sudden become kosher? And when state of Pakistan was/is supporting Afghan Taliban (to protect its own national interests) , I have seen many bad mouthing state .
