Islamabad was hopeful that under Taliban rule, anti-Pakistan terrorist groups, such as the Tehreek-e-Taliban Pakistan (TTP), would be restricted from operating in the neighboring country.

However, contrary to Pakistan's expectations, the Afghan Taliban have not only refused to take action against these groups but have also provided shelter to the TTP and its affiliates.

Three years on, relations between Pakistan and Afghanistan are at their lowest point, raising questions about the success of Islamabad's Afghan policy.

"I don't think this is a failure of Pakistan," said Pakistan's Permanent Representative to the UN, Munir Akram, in an interview with The Express Tribune.

Ambassador Akram emphasised that policies evolve with change of governments.

When asked, the veteran diplomat said the reason the issue of the TTP is unresolved is because of internal differences within Afghanistan.

The ambassador pointed out that organizations like Al-Qaeda and the TTP have had historical ties with the Taliban. While Pakistan has consistently sought a peaceful resolution to eliminate the TTP, the Taliban's internal issues have led it to adopt a seemingly softer stance toward this terrorist group.
