If the Taliban and Hizb-e-Islami had attended the Bonn conference in 2001, Afghanistan would not have become a battlefield once again, Afghan politicians said on Saturday.

The Bonn conference was held in late November of 2001 to decide on Afghanistan's future government after the Taliban regime was removed by US forces. The conference was attended by representatives of all of Afghanistan’s political parties except the Taliban and Hizb-e-Islami officials.

20 years after the conference, some politicians believe that the absence of these two groups caused Afghanistan to advance gradually into instability.

Sayed Ishaq Gailani, the head of the National Solidarity Movement of Afghanistan, said: "We told Zalmay Khalilzad at that time to invite the Taliban and Hizb-e-Islami to the conference. He said 'they are not coming.'”

Meanwhile, other analysts said that the Taliban seems to be making the same mistake by not including political groups and ethnicities to their new government.

They urged the Taliban to allow every ethnicity and political group to take part in the government.

Freelance Journalist Abdul Hai Sahar said: “The Taliban was not at the conference ... they now formed a cabinet which is not acceptable for many Afghan people, politicians and the international community.”

Several residents in Kabul urged the Taliban to form an inclusive government and to not repeat the unsuccessful outcome of the Bonn conference.

Noorullah, a Kabul resident, said: “The government that formed after the Bonn conference was not working for Afghanistan, instead, the government was working for its own benefit.”

Residents say forming an inclusive government seems to be the only way to end the conflict in the country.
