What occurred in South Asia was, to believers of supreme beings, an act of god. This is clear since we have credible historical evidence proving that Tsunami's manifested themselves many hundreds of years prior to man's ability to fabricate one, (the nuclear era).

Since it is an act of god it is clearly an act of Allah since, per your belief, Allah is the one true god. It is therefore inconceivable that it was an act of a Judeo-Christian god.

Of all the places in the world Allah could have chosen he chose to have it happen in a region where it would cause the most death and destruction to his own believers. He could have chosen the US Pacific coast for example.... But he didn't.

An act of such massive destructive force can only be attributed to an angry god. One that is disapproving of something. Since it was directed specifically at his own followers it is reasonable to assume that his anger is pointed at those followers. Even if you were to argue that this was a "natural event" Allah could have stopped it but chose not to even though it targeted his followers at a time in history where such an event might be seen as a sign of anger.

Mr. Bin Laden: I believe you might need a quick chat with your god, I think he might be trying to tell you and your followers something..... Think of it as a big PM.... You need to respond, Allah may have asked for a read receipt!
