Changing gears from cyber security to the tangible world, 2015 saw one of bloodiest years on record since the end of World War II. Terrorism that originated in Middle Eastern conflicts has spread out and is beginning to become commonplace in Europe and even starting to appear, yet again, in the United States. The Charlie Hebdo and November 2015 Paris Attacks, along with a third attempt foiled by the presence of American military veterans rocked Europe as the world mourned for them. In the US, a similar, though far less attack, took place in San Bernardino, California. Between these three major attacks, around 160 people were killed. This, however, pales in comparison to the world-wide effects of terrorism. In total, there were nearly 400 terrorist attacks around the world that we know of . In that, it is likely that more than ten thousand people lost their lives in acts of pure terror. I say pure terror, not to add drama to the point, but to differentiate these acts from the similar acts of violence. Acts of warfare, kidnapping, and social strong-arming are being ignored, as their practice has exploded in the last decade to unestimatable levels.
How this will affect the world in the next twenty years is that people, meaning nations, firms, and individuals, will be taking greater steps towards ensuring their own safety in the event of attack. For many, this will see annual trainings being required at many workplaces and schools. Many are already doing this. In another answer, I described how the last decade of terror and threat of “active shooters” has led to new methods and tactics aimed at empowering the individual victim to better deal with theses threats in a way that mitigates their danger, or when cornered in the worst case scenario, confront and attempt to neutralize the attackers. One such training program is ALICE, controversial in that it actually coaches victims of an active shooter incident to fight back as a very last.
