1. The Taliban originally came from pashtun nationalist who taught a long side with the mujahideen, but we’re radicalized by sunni extremism taught by madrasa near Kandahar. These schools were funded by the United States and Saudi Arabia who agreed to match the US dollar to dollar in funding the counter insurgency in Afghanistan.

I believe you are talking about Al-Qaeda

The Taliban’s roots lie in the religious schools of Kandahar and were influenced significantly by foreign support, particularly from Pakistan and Saudi Arabia, during the Soviet–Afghan War.

Additionally, both Saudi Arabia and the United States shared common geo-political goals such as countering the influence of the Soviet Union during the Cold War.[31] The Saudis’ increase in oil production to stabilize the oil price and its support of anti-communism contributed to closer relations with the U.S.[27] In January 1979, the U.S. sent F-15 fighters to Saudi Arabia as part of its anti-communist campaign.[27] Furthermore, the U.S. and Saudi Arabia were both supporting anti-communist groups in Afghanistan and various countries.[33]

After the Soviet invasion of Afghanistan in December 1979, relations between Saudi Arabia and the United States further strengthened as both governments began jointly co-ordinating to assist Afghan resistance militias, which waged guerilla warfare against Soviet occupation forces across Afghanistan.[31]

2. Who was funding Pakistan…?

President Reagan’s new priorities and the unlikely and remarkably effective effort by Congressman Charles Wilson (D-TX), aided by Joanne Herring, and CIA Afghan Desk Chief Gust Avrakotos to increase the funding for Operation Cyclone. Aid to the Afghan resistance, and to Pakistan, increased substantially, finally reaching $1 billion. The United States, faced with a rival superpower looking as if it were to create another Communist bloc, now engaged Zia in fighting a US-supported war by proxy in Afghanistan against the Soviets.

3. The US never supported the Taliban.

Yeah, they were pretty much funding any anti-soviet forces in the region.

After the Soviet Union invaded Afghanistan in 1979, the United States in coordination with regional partners such as Saudi Arabia and Pakistan launched a covert campaign, Operation Cyclone, to support the Afghan mujahideen resistance to the Soviet occupation. While American funding for weapons and military equipment for the mujahideen is well known, many are unaware of the significant expenditures by the American government through USAID to provide educational materials and textbooks to mujahideen parties and Afghan children.4 Published and distributed by the University of Nebraska-Omaha (UNO), this program attempted to encourage a violent resistance to Soviet forces in Afghanistan by shaping the educational program of Afghan youth. However, the content of these textbooks blatantly promoted jihad, militancy, and violence through graphic language and imagery. The textbooks included clear messages aimed at evoking hostility towards Russian invaders and promoting violent retribution against occupiers of Afghanistan. Textbooks designed to teach children to read and basic mathematics simultaneously emphasize weapons, killings, jihad, and Islamism. Although American officials claimed that they did not want to impose American values on Afghan educators, their failure to question the radical content presented in the textbooks reveals how countering Soviet communist influence transcended the potential destabilizing consequences of this program on the Afghan political situation. This intervention in Afghan education is emblematic of a broader pattern in how American policymakers fail to consider the long-term ramifications of their actions on the everyday lives of the Afghan people.
