The United States left Afghanistan after spending trillions of dollars on "democracy promotion" and "nation building" in vain, an inglorious event which also signals the end of the US hegemony, said Benyamin Poghosyan, chairman of the Center for Political and Economic Strategic Studies, Yerevan, Armenia.

Poghosyan said the key issue in Afghanistan is the interests of the Afghan people, and that, the Taliban government should be inclusive and take concrete steps to fight terrorism, which can help promote peace restoration in Afghanistan.

Poghosyan said other countries should make constant efforts to help Afghanistan and Afghan people get through the crisis.
