I don't actually think that any of us are in any position to criticize government action on the intelligence front as none of us are privy to what goes on between nations at international level. We can only make a judgement by what the media churns out, some of which can be a bit dubious. It is the prime duty of any government to protect and defend all its citizens, and, thank goodness we have a government that acted immediately, when alerted, to do exactly that. What would people have prefered? business as usual while politicians dithered around, with a meeting here, and a bit of hand wringing there, as another plane was blown out of the sky?!! We give the terrorists enough to laugh themselves silly over at our expense on a depressingly regular basis, without giving them another incident on a plate to congratulate themselves over.
