I posted a few, but you can read all here:
http://news.bbc.co.uk/2/hi/talking_point/4207856.stmThe power of Katrina could not have been fully predicted but from an outsider the actions of the United States has been astonishing. How could the wealthiest country in the world get it so wrong and abandon its people?

The US administration is preoccupied with affairs of other countries more than that of its own. This is the biggest mistake needed to be corrected.

I find it outrageous that the Red Cross and other relief agencies are asking for donations to help with the relief. The USA is one of the richest countries in the world, who are capable of spending vast sums of money sending soldiers to invade other people's countries, but who cannot deal effectively with a disaster in their own country.

I watch with horror as this tragedy unfolds on the television. This truly shows that the American dream only applies if you are white and well off.

They are the most powerful nation in the world. They had advanced warning of a possible catastrophe. Yet four days on the best Bush can say is that 'food and water are surging towards the area'. It is an absolute disgrace. Water should have been dropped immediately. If planes can be sent to Iraq, surely they could be sent a couple of States! The governing forces in America should be ashamed.

Shame on the Bush administration for putting pride above the lives of Americans. Paul Martin has offered the help of the Canadian army yet Bush has not responded. Would it hurt his ego to accept help from an army that is available because it did not join his little war in the Middle East? Or is it because the majority of the victims there are poor and black? What is he waiting for?

This will do more damage to America's reputation than the Iraq debacle. If they can't rescue their own people in their own country why should the rest of the world believe they can be relied on to do anything?

Perhaps I'm stupid, but how can Bush demand people give generously to aid agencies when he holds the purse strings of the richest country in the world? They found the money to go to war in Iraq and yet, he wants his own people to pay towards saving one of the best, most unique and most colourful cities in the US.

I have been watching Katrina response on TV for the last few days, and I have two observations: The first question is why those affected are all from the black community? Secondly, why is the US government sending the National Guard with the authority to shoot, rather than provide support to the victims? I believe that the US government attitude has added to the suffering of the victims

The response to this disaster has been so inept, it would shame a Third World banana republic. It is indeed a national disgrace and it proves conclusively, if proof were needed, that George W. Bush is not up to the job of leading what is the greatest nation on Earth.
