Muslim terroists dont have any country sentements.They will kill all citizens with same glee, even if they are his own countrymen in the conventional sense.
It is time the world realises that and stop focusing on countries and focus on muslim terrorists.
The moderate islamic community themselves need to get actively involved in formulating a reporting helpline for its youngsters to report on abnormal activities taking place in their vicinity/ among friends.
The close friends/ wife of these terrorists might have had some sspicion earlier, but they would have found it much easier if they could talk anonymously to a muslim elder.It is a constructive way to prevent further carnage.
