Re: YES ! Pakistan was used.
^ so what If both terrorist org are different? They are anyway killing innocent people and islam doesn't permit both the idiology.
Beside I agree with many of the posters that War between two countries is not solution, Instead we need to focus on root-cause of the terrorism and 'brain-wash' them back to mainstream...
Hope somehow we can find out who are the financiers for these terrorist activities and stop them. IMO they are real culprit
