Scientists Want to Know: Is There Water in Tehran?

A few weeks ago NASA bombed the moon to see how much water would be present in the dust kicked up by the blast.  Some wags stated that the USA had declared war on the moon with a preemptive attack, and that Harry Reid immediately declared the war lost.

Now it appears that the test showed there is indeed water on the moon.  Why this is important isn't immediately obvious to me.

I know a lot of scientists, particularly Israeli ones, who are anxious to test for water in Tehran.
