After all, 18000 innocents dead at their hands, including 8000 children? Unless you think that's OK?   

Do you have a link for that claim?
I can see a statement of 18,800 deaths: Here but no comment about the number of children in that figure,

The figures may be accurate, as I see that the numbers of children seem to be higher (compared to the number of adults) than we would expect in UK. But if you're going to quote statistics then a source would be appreciated!
