It's all worth reading, but the part that caught my eye was this:
We generally tend to hear about the bombs that go off or acts of sabotage that succeed in destroying infrastructure, but almost never about successful prevention; for example, soldiers from the 208th Iraqi National Guard battalion who defused explosive devices attached to oil facilities in the Dibbis area; or a company of the 206th Iraqi National Guard battalion, which prevented an attack near Jalula. Some of other recent security successes of the Coalition and the Iraqi forces include: Iraqi Security Forces and elements of the 24th Marine Expeditionary Unit rounding up 41 insurgents in various operations south of Baghdad; smashing of a bomb making cell in Mosul; and the rescue of a kidnapped Iraqi by the Iraqi SWAT team, backed by elements of the 24th Marine Expeditionary Unit, in a raid in northern Babil.
The reason why this is so important I explained a year ago in my article on the Structure of Terrorist Movements. In brief, while a terrorist group can endure decades of political failure and defeat, it needs to strike effective blows to maintain itself as a movement:
Lack of operational success, however, has a much more immediate impact. Leaders and Soldiers who are incapable of striking effectively at the oppressors are not deserving of loyalty and sacrifice, and the humiliation of aquiescence is less unthinkable when set against the humiliation of losing in the field. Failed operations are acceptable when other operations bring successes to be celebrated, and one spectacular coup can balance a large number of embarrassing damp squibs, but a long series of symbolic defeats will sap at every level of the movement.
The terrorist army in Iraq is still achieving enough operational successes to avoid total defeat, but not, I think, by a large margin, and Chrenkoff's list shows that they are only doing so by means of a frenetic rate of more or less reckless attacks, most of which fail.
The question of the effects on the terrorist movement of attempting to maintain this rate of activity deserves some attention. I cannot think of a precedent, even among the most similar movements such as Hamas or the Egyptian Islamic Jihad.
