Security challenges in a modern world are definitely different than in history. There is no person who can say that traditional security challenges (like wars and armed conflicts) does not exist, but still, contemporary security challenges that effect most of the globe are much more diverse than before. Terrorism and transnational organized crime are the most visible threats but beside that, we have others, whose influence on the security we cannot exclude. Climate change, poverty, media, social networks, politics, religion, health care, and many other issues. Humanity is now, more than ever, in danger and constant fear of, pollution, climate changes, overpopulation, nuclear catastrophe, etc. In that manner, we can say that every serious and responsible government have to take seriously these challenges.
