I share the hon. Gentleman’s scepticism in this regard. Last Thursday I asked the Prime Minister whether he envisaged circumstances in which the Free Syrian Army and the Kurds would launch a successful ground offensive against Daesh, ignoring the presence of the Syrian army or pretending that it was not actually there. I did not receive a satisfactory answer.
It seems to me that a four-way civil war is taking place in Syria, and that some of those four sides are themselves quite complicated coalitions. If we are to develop a Daesh-first strategy, we shall need to persuade the other three sides to agree to co-ordinated action against Daesh. That is where the focus of diplomatic and political effort should be directed. I realise how difficult it will be. I realise that many of the groups that are associated with the Free Syrian Army, for example, would see Assad as more of an enemy than Daesh, and it will take a great deal of negotiation to bring all that together. It does not mean that all those groups must share a command structure, and it does not mean that they must share zones of operation—those can be separate—but any action must be co-ordinated. We cannot allow a situation in which some of them are simply trying to do what would be our bidding in a completely irrelevant and ineffective manner. That strikes me as a recipe for disaster.
The one hope in all this is the Vienna process, and the fact that a dialogue is under way. We believe that the time now should be spent in boosting that process, and in trying to secure the political and diplomatic agreements that we need for co-ordinated action that will be successful not just in bombing places into the stone age, but in taking control of land, starting with a military administration and then passing it over to civilian administrations month by month, year by year. Unless that framework is in place—and, unlike the Chairman of the Foreign Affairs Committee, for whom I have a great deal of respect, I remain to be convinced that it is—when the opportunity comes on Wednesday, the Scottish National party will not vote to go to war with Syria.
