Post-battle. Population returns/comes out and a spurt in births ensues leading to more defects naturally. Ontop of other factors- marrying within tribe/sect within a certain geographic area and said resulting chemicals in the water supply then yes.
How many people in Faluja? Simpsons said it was a very small town.
From the battle at the time I was under the impression that it was both strategic and a large/prominent town in Iraq?
Basically I think its a combination of factors. Every war shows a growth spurt in newborns.
Its disingenuous to report this way. Reminds me of the BBC's reporting on the Serbs portraying them as all bad in the Bosnian war.
