Didn't think it was worth quoting I'm afraid.
My analogy would be a boat inspector who is determined to find and remove every rotten timber in a wooden hull. That is fine in dry dock but not necessarily that clever at sea in a force 10.
In the context in which you sought to use it, it's a poor analogy.
It does however work fairly well when you look at the reality of our actual situation.
We are fighting a force that doesn't play by our rules in a war where our sole justification is to try and persuade the local population that our rules are the ones people should be playing by.
If your man rips out the rotten wood, your ship sinks. If our rules are ripped out, we lose our justification for fighting. So in that way your analogy works a dream. But I didn't think that was what you were driving at.
