Attempts As Both Tactics and Strategy
John Robb's Global Guerrillas has an interesting alternative perspective on the crotch-bomber's attack and the reaction thereto.
I differ from Robb in his nomenclature, as I believe the term "attempt" better describes the swarm-attack tactical/strategic opportunity he discusses.
More on swarming here, here, here, here and here. Saul Alinksy's Rules for Radicals also implicitly acknowledges the power of swarms in Rule 8:
8. Keep the pressure on with different tactics and actions, and utilize all events of the period for your purpose.
As dessert, you may also want to read this after-action report on the swarm attack war-gamed against the US Navy in 2002.
Food for thought:
Especially in asymmetric warfare, if a "failed" or "attempted" attack causes the OpFor to extend and deplete resources such that other near-simultaneous attacks are more likely to succeed, has the "failure" actually failed?
Phrased alternatively, ask Admiral Yamamoto about the failed attacks of VT-8 from Hornet and VT-6 from Enterprise near Midway Island on the morning of June 4, 1942.
