Thoughts are with all the families touched by this tragedy of course. Since those attacks what do you think has been achieved and equally what do you think has become worse?

Osama is dead - a powerful and haunting face of Al Qaeda sure, but also a great tactician apparently.

Where do you think Al Qaeda stand 6 years on as we prepare to pull troops from the middle east?

Also, how do you think they will stand on the 10th anniversary of 7/7?
