The decision that we will take today is the most difficult that this House could face: whether to commit our armed forces to conflict. I believe that the use of military force must be a last resort. We must resort to military force only when all political, economic and diplomatic routes have been exhausted. However, the complex nature of the threat that we face and the evil perpetrated by ISIL cannot be confronted by political, economic and diplomatic means alone.
During the debate, it is important that we consider the lessons of history and understand that, whatever we decide, there will be consequences. We know well the possible consequences of military action. We will be entering a situation that we cannot fully control. Nor do we know for certain where our involvement will end. In the short term, we should be prepared for the fact that it might increase the risk against our country. ISIL cannot be defeated overnight and we will need fortitude and resolve over the coming days, weeks, months and potentially years.
However, there are consequences of not acting, too. If left unchallenged, ISIL will continue to sow its seeds of destruction throughout the middle east. Its ambition, though, is not limited to Iraq and Syria. It has already murdered a British citizen and if we do not confront it now, its murderous activities in the region could be exported further afield, including to our shores. Therefore, having very carefully considered the different courses of action, based on the information presented, I believe that the risk of not acting is greater. But if we are to act, we must ensure that our intervention conforms to certain criteria—that it is legal, legitimate and proportionate—and that any use of force brings with it a clear prospect of success in defeating ISIL’s capabilities, and comes with a clearly defined mission, end-state and exit strategy.
We should be clear, however, that air strikes in Iraq can be only one strand of a much wider strategy and that on their own they will not be sufficient to defeat ISIL. Achieving decisive success is only likely to come through subsequent action, and from regional forces taking action on the ground in Syria as well as in Iraq. So we should play our part in helping to build and sustain the wider coalition from across the region, and we should provide support to those contributing partner-nations where we are able to do so. However, there needs to be a wider, encompassing political framework, with a clear plan—both for the immediate aftermath and the longer term—to provide humanitarian aid and reconstruction.
