One big problem is that we all have become so accustomed to it that whatever happens somewhere, we express our condolences and then at some point we forget everything whereas those who foster terrorism need to be eliminated from the roots because today you may be safe but there is no guarantee that you will be safe forever because maybe you do not know it, but according to the Islamist Ideology, no non-Muslim has the right to live in this world and this is what they teaches them since childhood that either convert or kill them. By being surrounded by people with such mentality, try to imagine the future, it will be no less than a scary dream.
