In 1988, Iran strengthened and united several of these Hazara factions into the Hezb-e Wahdat-e Islami or Islamic Unity Party, and Tehran continued to support the organization during the Afghan civil war that followed the Soviet withdrawal in 1989.Wary of a Sunni-fundamentalist Pashtun state on its eastern border, Iran viewed the rise of the Taliban in 1994 and their seizure of Kabul in 1996 as a serious security, ideological, and economic threat.
While the Iranian leaders welcomed the fall of the Taliban, they also saw the presence of American troops in neighboring Afghanistan as a national security threat.
Tehran’s support for insurgent groups in Afghanistan, including the Taliban, has been a source of great anxiety for the ISAF and Afghan forces struggling to stabilize Afghanistan.
The Baluch are another ethnic group that lives in Pakistan, Afghanistan and Iran.
The Baluch constitute two percent of the Iranian population or roughly 1.3 million people.
But when a US-led coalition invaded Afghanistan in 2001 to overthrow the Taliban, Iran was not disappointed.
