Mr. Derek Moran:

The reality is that bringing exercises of this nature up to this type of level gives them an authority they might not have had historically when they were conducted by groups like the domestic standing group. The Deputy's point is very well made. The role of the group is to look at things that we almost cannot conceive of happening. It is a question of the extent to which we can look through crisis simulations. The real dilemma is that when one is preparing for the next crisis, one is really only looking at the last one.
