Weapon can kill one terror perpetrator, but cannot kill the hatred that become the cause of terrorism. Then next day two new terror perpetrators will appear. So, we must 'kill' the hatred. And the best way to 'kill' hatred is teach the love.
Teach our children to respect the difference, respect the others. Teach our children to have empathy which they can feel what the others feel. Teach them about social care. And if they can feel a happiness when doing a kindness to the others, In Shaa Allah, hatred will never come to their hearts.
