Phosphorus is a terrible weapon,but so are many others.The thing that i dont approve is that why did US had to use phosphorus in a area where they knew that population was still mostly there. I remember how the Russians were critizised off using artillery against villages in Tzechenia, how does this differ from that.I think that both US and Russians target was to kill the enemy fighters ,but they both also knew they would kill more civilians in the process then necessary. Have anyone ever thought what would happen to a person who would try to leave his home in Iraq in order to run away from an fighting area,and the insurgent fighters would notice that? He or she would be most likely be treated as an traitor and killed.
So i feel sorry for those innocent civilians in Fallujah,they had two great choises ,to die from a bullet or die burning inside a green flame.
