The Battle of Fallujah in Iraq in 2005 was on of the most brutal reprisals by the Americans during the Iraq war. There were claims of white phosphorus bombs being used as well as depleted uranium weaponry, (an anti- tank type of weapon, though Fallujah had no tanks). The town was obliterated and its population decimated. Since then the area has had an extremely high proportion of birth defects and cancers. This crime against humanity has been ignored by the Western media, even although there has been a high incidence of similar problems amongst the US personnel involved in that brutal crime.
The most barbaric terror inflicted on any people is the terror of the state, there is no more powerful terorist organisation on the planet than the state. War is just terorism with a much bigger budget.
