Taliban was created in 1994.
Yankees went home in 1989 after the USSR went back from Afghanistan.
What was happening during the intervening period? Those "Mujahideen" were killing each other and the ordinary Afghans which had nothing to do with USA or any infidels.
Are you really serious? Where is the Queta Sura? Where are the Haqqanis based? What is happening in North Waziristan?
Where is Mulla Umar hiding? Where was OBL hiding? Where did all the AQ and Taliban terrorists flee to?
You really need to get your facts correct. Mullah Umar, Haqqani, almost all the terrorists that are part of the Taliban today were part of the Mujahideen. So yes, the US was responsible for the creation all the terror groups, which includes the AQ, Taliban, Northern Alliance, Hizb-e-Islami Gulbideen, IMU & others.
Again, how does that show the ISI is supporting these groups? The Mehsuds, Molvi Faqir Mohammed, Abdul Wali, Qari Zia Rehman, Mangal Bagh of Lashkr-e-Islam, Maulana Fazlullah, Mullah Nazir & others are all comfortably living in their safe havens in Kunar & Nuristan; the NATO Forces specifically abandoned their outposts & let terrorists recapture districts in Kunar. Does that mean that the NATO/US Forces/ANA support these terrorists?
The Taliban have denied Mullah Umar is in Pakistan, read the reports man before spewing baseless claims. When false reports came out in the media about Mullah Umar being killed, the Taliban denied it straight away, & said Mullah Umar wasn't even in Pakistan; he was in Afghanistan, & has been in Afghanistan the whole time. That just rubbishes all the speculation you're mentioning.
The heartland of the Taliban is Kandahar, Mullah Umar lives there, they infiltrate into Pakistan with impunity, which is why you see attacks in Quetta in Balochistan all the time. Is it a coincidence that 470 Taliban were pretty much let go in the Kandahar prison a few months ago, under everyone's nose? Does that mean the NATO/US Forces support the Taliban?
The Haqqanis have their base in Khost & Paktia in Afghanistan. In North Waziristan, the border is porous between Khost & North Waziristan, so the Haqqanis infiltrate into both regions quite a lot. All the AQ & Taliban terrorists have fled into Afghanistan, you really need to update yourself man instead of regurgitating your baseless propaganda.
