Iranian Missile Crisis

Saw this headline and can't help wondering what all the fuss is about. I mean, if it takes that long for an Iranian Missile to get to America it must going really really slow. Even a guy in a micro light with an air rifle could probably get up there and shoot it down. I have a better idea Iran. Why don't you get DHL to deliver your missile. They could get it to America in a few days.
If the Iranians really want to cause carnage in the west they should talk to Iceland about borrowing one of their volcanoes. How many more do they have hiding under the glaciers? And speaking of glaciers, I thought Al Gore reckoned they would all be gone by now. Maybe if global warming was a little more advanced and all the glaciers were gone we would be able to spot those troublesome volcanoes that have been hiding under the ice.
