There is no quick solution to this dilemma; a disposition of peace amidst a climate of terror? Many were deceived by that “light at the end on the tunnel” which turned out to be a speeding train set upon its course! Terror is always sudden and violent; otherwise it would be called Diplomacy!
Here is my two bits worth: God says in the Holy Quran that His love for us EXCEEDS that of seventy mothers. There is no indication anywhere that this declaration is exclusively reserved for Muslims! So why can’t we begin to love each other, even minimally, with the love of only ONE mother as a start? What qualifies us to judge one another when we have dirt on our own backs?
God also says there is no compulsion in religion BUT IF anyone should prevent you from worshiping Him, ONLY THEN is war justified. And He prescribed strict rules for engagement promising severe punishment for circumventing them. I don’t see anyone preventing another from worshiping, do you?
