I too don't think his inspiration will do much. Why? No Causation.

In America many complain about the government, but we recognize it's legitimacy and we believe in our ability to control it, vice the other way around. This is what immunizes a populace from Insurgent motivation, be it ideology, leadership, or acts like this.

Most populaces don't have anything even close to what we enjoy in America in this regard; but I assess downward trends on both of these critical metrics over the past 20 years; and that is a trend we would be wise to address sooner than later. Good COIN is done years before the acutal insurgent is ever even born.
