TTP was formed when TTA was not in power and USA was there . We have taken many steps since 2001 to secure our borders esp after 2011 and more importantly after 2014 . Are these highlighted parts apply to Afghan Taliban only or Iran's proxies in Iraq , Syria , Lebanon , Yemen e.t.c as well .Guy, come back here and repeat your nonsense when you completely destroy the TTP in your own land.
If Taliban tries to fill the gap by enforcing its ruling system over people of Afghanistan, then the country will experience civil war even worse than the past, millions of refugees will end up in your borders, everyone having slightest ideological problem with your country, would try to recruit them and hence unrest in Pakistan. Zarif despite being an imbecile is right in that case. Talibs should be under control of people chosen government, drop their weapons and try for peace in the country. Government should also consider their wishes and allow them to have their own lives.
Iran itself never defeated its anti state or terrorist groups in its country along borders and within it . focus on yourself before lecturing us . Iran supported Northern Alliance in 1990s as well . Dont present yourself as an Angel .
