How war has changed due to Terrorism

War has changed a lot since the age of terrorism. With the increasing involvement of terrorists around the world, war has become much more severe and threatening. Terrorists innovate, exploit new technology, learn from one another, imitate successful tactics, produce manuals of instruction based on experience, and justify their actions with doctrines and theories based on religion. Due to this we can recognize several drastic changes and trends within terrorism. It has become bloodier, in terms of what acts are committed and how many victims are involved. The order of magnitude has increased almost every decade. For example, on 9/11, there were thousands of fatalities, and there could have been far more. We now think about scenarios in which tens of thousands might die. Terrorists have also developed new ways of financing their operations so that they are less dependent on state sponsors. They have evolved new models of organization and can now wage global campaigns. They have successfully exploited new communications technologies to use and some of them have even moved beyond tactics to strategy, although none of them have achieved their stated long-range goals. The course of terrorism is unpredicted which is what makes it so hard to be prepared for a terrorist attack because it is unexpected and you never know when they will attack again. The only way to cope with this sever matter is to incorporate more and more security measures around the world.
