Just came across this story from last week in a blog called Lockandload:
This is one of the unintended consequences you get when muslims are allowed to enter western society: a refugee who became a Swedish citizen only to go to Iraq as a terrorist and attack the government. Fortunately, he was recently killed in fighting there.
This case illustrates the long time that terrorists have been infiltrating the West and using Western society to advance their plans.
