Do you have proof the Taliban was that fucking stupid to believe that the Pakistanis and Saudis coming into their country to stay in military style training camps for a month, which were ran by AQ, that they have no idea what AQ is or what they are doing? Please.
Do you have proof they knew what they were planning? Its far more likely they knew that they were training to fight infidels in their own lands.
Who knows what they knew but I don''t believe they knew they were planning 9/11 and probably didn't like it one bit they pulled it off and brought everything on them.

The Taliban knew AQ were a terrorist group, and they knew they were training in their country.
Not for one second did they ever consider them a terrorist group.

The IRA, and AQ are different. I think you answered our question. You can't just invade a country just because you got some ass kissers in that country. Who gives a shit what we did 200 years ago? The US government did not willingly let the IRA build training camps, we actively hunted them and arrested them...
You would be surprised how many Americans of Irish ancestry remember the events of the British making it illegal to even speak Gaelic and the subsequent events that transpired.
So heinous were those actions that there is alot of collusion between the nazis and Irish, shockingly so.
You just made my point by not considering what we did compared to what they did.
