As the whole war is unleagal as well as the occupation, I do not see any problems in killing scumbags from either ITALY, POLAND, BULGARIA, DENMARK, UK, USA, SPAIN, etc, etc.
No matter if they would be civilians. They do not have any buisness in Iraq, what so ever.
Have it accured to you that the war might never really ended just because Bush said it was over?
Bring Bush and Blair to Haag for the warcrimes they have commited.
