I think that the point at which ISIL can no longer act with the menace and brutality with which it acts at present will be quite obvious on the ground. However, as many people have pointed out, we are not pretending, and no one should pretend, that air strikes on their own are the solution. That is why I want to address myself to those—including the right hon. Members for Croydon South (Sir Richard Ottaway), for Neath (Mr Hain), the hon. Member for Sheffield, Heeley (Meg Munn), the right hon. Member for North Somerset (Dr Fox) and the right hon. Member for Sutton Coldfield (Mr Mitchell)—who have suggested that we should now take the decision also to embark on air strikes in Syria.
It is important to remember that, as has been pointed out by the right hon. and learned Member for Beaconsfield (Mr Grieve) and others, there are complexities in Syria which are not present in Iraq. There are differences. The fact that we are not embarking on air strikes in Syria does not mean that we are inactive in Syria. We train, equip and advise the forces in Syria whom we wish to support in Syria. In one sense, by choosing to play one part in the wider jigsaw of this coalition effort that now comprises 60 nations undertaking different forms of action—military, diplomatic, political and humanitarian —we are saying quite overtly that we are doing one part of what we judge we can do best right now, but not pretending that we can do everything all at once. Just because we cannot do everything does surely not mean that we do nothing, and that is the sensible stance that we are taking.
