Not to mention that according to CNN:

"Thousands of people have been sleeping on streets, interstate access ramps, bridges or any dry spot they can find.

Outside the New Orleans Convention Center, a huge crowd waited on the sidewalks for aid that could be a long time coming. The building was used as a secondary shelter when the Louisiana Superdome was overwhelmed."

Those people will need water and food now...

Still, I do understand your point.

It troubles me that, at least in the foreign press, it appears Bush is not asking for help.

One point of this thread was showing Americans that foreign countries and foreign aid organisations are willing to help. Even if we´re not needed, we´re offering it. It worries me in return that a lot/some Americans seem to be thinking that we don´t want to help.
