Marines under mortar attack, crying for their lives...
http://www.youtube.com/watch?v=RZlvLmBvOx8 Then, Imagine the Iraqi's civilians reactions being bombarded with Cluster Bombs, JDAMs, Napalms, WPs and 2000lbs bombs from B52s.
Dying from Napalms (disregarding whatever the US saying it's not Napalm because they subsituted petrol with kerosene) is the most horrific way to go. Because it is very painful, takes a very long time, and after burning to crasp, your heart keeps pumping for a few minutes more.
Iran should start producing Napalms, should US invade them and let the Americans population see what they are doing to the world.
