@Walter Hinteler,
You seem to be conflating both Mujahideen and The Resistance with The Taliban.
If Karzai made no secret about being an advisor to the Taliban, the quote you've provided from your linked article doesn't suggest that. It says that he was an advisor and diplomat for the resistance. The resistance movement during the Soviet occupation is not synonymous with the Taliban. Members of the Taliban, formed by Omar in 1991, undoubtedly were among those called the Mujahideen and part of the resistance movement but they weren't the only ones and they didn't exercise control over it.
The Afghan resistance movement began in the late 70's and was initially directed against the pro-Soviet DRA, when Soviet troops were sent to support the DRA and occupy the nation, the resistance obviously focused on them and the Soviet's War in Afghanistan (1979-1989) was on.
Initially, the resistance movement that began against the DRA and extended to the occupy Soviets (1979-1989), was led by local warlords and confined to their geographical locales but in 1981 the Islamic Unity of Afghanistan Mujahideen was formed by the joining of the following individual Mujahideen groups:
Hezb-e Islami Khalis - led by Mohammad Yunus Khalis (Supporter but not member of Taliban)
Hezb-e-Islami Gulbuddin. led by Gulbuddin Hekmatyar (Opponent of Taliban. Eventually fled to Iran to escape them)
Jamiat-i-Islami - led by Burhanuddin Rabbani (Opponent of the Taliban and was eventually assassinated by them)
Shura-e Nazar - led by Ahmad Shah Massoud, (Opponent of the Taliban. Eventually assassinated by al-Qaeda, supporting the Taliban in advance of the anticipated attack by the US)
Islamic Union for the Liberation of Afghanistan - led by Abdul Rasul Sayyaf (Claims he was opponent of Taliban, but there is evidence of ties with al-Qaeda. May have assisted in assassination of Massoud.)
National Islamic Front for Afghanistan - led by Ahmed Gailani (Opposed the Taliban)
Afghanistan National Liberation Front - led by Sibghatullah Mojaddedi (Spent the period of the Taliban rule in exile)
Revolutionary Islamic Movement - led by Mohammad Nabi Mohammadi (Supporter of the Taliban. Many of his students were original members)
You'll note the absence of the Taliban and Mohammed Omar, as an originating group or as a leader from this list.
The following might have better supported the statement that Karzai worked with or for the Taliban
Quote:The Taliban movement sought Karzai's support in restoring order, and offered him the post of United Nations ambassador, but he broke with the new regime when it fell under the influence of foreign terrorists.
It fair to say that Karzai, at one point, had some favorable regard for or ties with the Taliban
Quote:When the Taliban emerged in the mid-1990s, Karzai initially recognized them as a legitimate government because he thought that they would stop the violence and corruption in his country. He was offered by the Taliban to serve as their ambassador but he refused, telling friends that he felt Pakistan's Inter-Services Intelligence (ISI) was wrongly using them. Reports suggest that the Taliban carried out the assassination (of Karzai’s father). Following this incident, Karzai decided to work closely with the Northern Alliance, which was led by Ahmad Shah Massoud.
From what I have read on the web there is not unanimity among sources regarding when the Taliban formed but the majority agree with the Wikipedia article Baldimo cited that the group was established after the withdrawal of Soviet troops from Afghanistan (1989) and indicate sometime in the early 1990s. A number of these sources though write of the origin as the "emergence" of the Taliban, which could imply prior existence as a relatively unknown group.
What seems to be clear though is that the Taliban was not recognized as a major force during the period of Soviet occupation. They were not among the originating members of the Islamic Unity of Afghanistan Mujahideen; and their purported founder Mullah Mohammed Omar, did not lead any of the groups. While two of the originating leaders can be described as having been Taliban supporters, at one time or another, the rest were opponents, with two being assassinated as a result. Even the two supporters are not said to have even been actual members of the Taliban, whether early on or more recently.
