When children are the victims we all tend to be outraged and want the worst possible *punishment* for the perpetrators. Justice is what is required here, not revenge.
When it comes to terrorists the entire world needs to come together as one entity against terrorism. The entire world needs to cooperate to end this for good.
Those dead children in Russia, the 3000 dead from 9/11 and all the other victims of terrorists need to be remembered by all people, not just their families and countries.
