Depending on who you ask, God sent Katrina either to punish the US for supporting Israel's disengagement plan:

On August 14, citizens in the United States, like people around the world, heard about the issuing of an order for the forced evacuation of Jews from parts of Israel's biblical land.

For six days they watched as thousands of weeping people were pulled and carried from their homes, forced to leave their gardens, parks, communities, schools, towns and synagogues, everything they had spent decades building; banned from ever returning again. Those scenes were soon followed by pictures of bulldozers and other earth-moving machinery pulverizing the just-vacated homes into heaps of dust.

While this was taking place, a small tropical depression was forming near the Bahamas in the Atlantic Ocean. Slowly, as the air began to revolve, the nonthreatening weather system began moving in the direction of Florida.

Yesterday, we in Israel watched as American officials, including President George W. Bush, ordered the mandatory evacuation of New Orleans and its surrounds. That small depression had turned into a frightening fiend. Now we are seeing on our television screens up to a million people being forced to leave their homes. People are weeping on camera, mourning that they are going to lose "everything we own; everything we have worked for."

As today unfolds we are bracing to see wind and water pounding homes, whole communities, into the ground.

Is this some sort of bizarre coincidence? Not for those who believe in the God of the Bible and the immutability of His Word.

What America is about to experience is the lifting of God's hand of protection; the implementation of His judgment on the nation most responsible for endangering the land and people of Israel. (Jerusalem Newswire, Aug. 29)

Or, Allah sent Katrina to punish the US for its imperial endeavors:

"When the satellite channels reported on the scope of the terrifying destruction in America [caused by] this wind, I was reminded of the words of [Prophet Muhammad]: 'The wind sends torment to one group of people, and sends mercy to others.' I do not think — and only Allah [really] knows — that this wind, which completely wiped out American cities in these days, is a wind of mercy and blessing. It is almost certain that this is a wind of torment and evil that Allah has sent to this American empire. Out of my absolute belief in the truth of the words of the Prophet Muhammad, this wind is the fruit of the planning [of Allah], as is stated in the text of the Hadith of the Prophet.

"But I began to ask myself: Doesn't this country [the U.S.] claim to aspire to establish justice, freedom, and equality amongst the people? Isn't this country claiming that everything it did in Afghanistan and Iraq was for truth and justice? How can it be that these American claims are untrue, when we see how good prevails in the streets of Afghanistan, and how it became an oasis of security with America's entrance there? How can these American claims in the matter of Iraq be untrue, when we see that Iraq has become the most tranquil and secure country in the world?

"But how strange it is that after all the tremendous American achievements for the sake of humanity, these mighty winds come and evilly rip [America's] cities to shreds? Have the storms have joined the Al-Qaeda terrorist organization?

The latter article, by Kuwaiti official Muhammad Yousef Al-Mlaifi, ran Aug. 31 in the the Kuwaiti daily al-Siyassa, according to MEMRI. It was titled, "The Terrorist Katrina is One of the Soldiers of Allah, But Not an Adherent of Al-Qaeda."
