There’s an absolutely fascinating and, mostly, temperate and reasoned discussion going on in the comments to this post at Winds of Change. Keep reading. It gets better especially starting at around question #31. There are lots of interesting observations from several parties which, oddly, becomes more civil as the conversation progresses (an unusual dynamics in blog comments threads).
Check particularly comment #63. In that comment the commenter analogizes the War on Terror to the fight against fire-ants in and around Houston, Texas. His basic message is that the obvious strategy isn’t always the best one and courses of action have secondary effects.
Check it out.
