In respect of solution for terror; scientific struggle with compassion, love, reason, mercy, by putting out an effort without offending anyone, with a kind hearted approach is the key and scientific explanations would solve the matters fundamentally. Apart from that, if the other side feels like things are going on in an assertive manner, turning into a war of pride, it would be very difficult for them to be convinced. Scientific explanations and addressing the good conscience would be enough. - Harun Yahya
