As you really are a very stupid individual I will, out of pity, go through this again as I presumed, wrongly, you had some vague knowledge of the situation.
1. On Clinton's watch the Taliban came to power.
2. OBL took up with them.
3. The Sauids negotiated with the Taliban to hand over OBL in return for international recognition which the Taliban craved.
4. The Taliban agreed and were prepared to hand him over
5. The US embassy in Nairobi was bombed as was the USS Cole in Yemen.
6. In retaliation Clinton ordered rocket attacks on Sudan and Afghanistan
7. The Taliban were furious and cancelled the deal with the Saudis thinking the Saudis had hoodwinked them
Are you following all this.......good....fast forwrad to 9/11
8. GWB goes to the UN and asks for sanction for an invasion of Afghanistan after the Taliban refused to hand over OBL
9. The Taliban admitted....note you...admitted he was there but refused to hand him over saying there was no proof he was responsible for 9//11
10. When the bombing began they offered to hand him over but Bush refused the offer.
11. The Northern Alliance backed by the US and UK drove the Taliban from Kabul
12. A video shwoing OBL admitting responsibility for 9/11 was susequently found and released.
So your folowing statement is BS
