The Taliban have not ability to strike at the United States. Zip Nada Zero.
You might have tried to make this argument September 10th, 2001. But then 19 guys with box cutters proved to the world that they could.
Jeff has dealt with a lot of the points I would have. The Taliban was a partner with the guys that killed thousands of Americans. They have not changed their outlook. If you believe so, please post some sort of counter to the words of their leader I have posted. They are still partners as far as we know and it is reasonable to assume that they still work together for their mutual benefitand goals. If there were proof to the latter, I would like to see it.
The government of Afghanistan is asking for our help to defeat them. It is in our interests to do so. I assume you would have us just sit back and let the Taliban defeat the government of Karzai and come back into power.
I also would think that your do not believe that the Iraq war is a drain on the hunt for the real terrorists. I do not know if you have made that claim in the past, but I am reasonably sure that when others have said so you have not countered them. I think this thread has helped illustrate your belief that we should turn the military operations totally over to the locals and leave the hunt for Osama to the nations that he is in.
