There's the old story about the man who lost his keys on a dark night, and was found searching for them under a street light. "But you didn't lose them anywhere near here. so why are you looking here?" "Because there's a light here and I can see to look."

A few years ago there was a terrorist bombing in Germany. So the USA and Britian cooperated in a bombing raid on Libya, to show terrorists they couldn't get away with it. The bombing was actually organised from Syria, but bombing Syria would have been politically inconvenient.

There's nothing we can say here that is going to in any way affect how our governments are going to act. Rather than speculating and saying what ought to happen, I think we'd be better to concentrate our attention on dealing with the anger and the pain and the grief in any way we can.
