Do nothing - move on to the next diary.

A vivid image of what should exist acts as a surrogate for reality. Pursuit of the image then prevents pursuit of the reality -- John K. Galbraith

I think you should do whatever you feel inspired to do.

The material here seems to fall into two categories:

1. First hand, or personal accounts of what 9/11 meant to people at the time - how they experienced it directly or through the media - and what impact it had on their own lives.

2. A more political analysis of how 9/11 was used to justify a major change in US foreign and domestic security and military policies.

These are two quite different topics, and I'm not sure which one you wish to develop.  I suspect that the moment has passed for 1. above - many accounts have already been written and compiled.

Topic 2.  above benefits from having more historical perspective and is an appropriate angle if you are looking at the Bush legacy.  I think it is a worthy topic for an ET "book", and, should you wish to pursue it - and would be happy to contribute.
