This passage struck me as applying here, although the theme is not small war(s) in the USA:
First, the American mass media, and as a result, the American public, simply does not have the attention span to grant a fringe ideology the time it needs to have a significant, long-term effect on the national conversation after only a single event. This is not ideal for a lone-wolf shooter whose goal is to draw attention to his political or social cause. As solo-actors, they lack a support structure for follow on attacks or media releases, which are essential to a coherent political terrorism strategy.
