Aleppo and Syria

I thank the hon. Lady for her intervention, because what she says is exactly right. Those who are killing civilians in Aleppo are relying on the fact that we fear escalation and we worry. People therefore do nothing. We did not know what the consequences of 2013 would be, and we worried about intervention. However, we know now, and accordingly, we know what will happen in Aleppo over the next few months if nothing is done. That is the point that we have reached. Ultimately, we are talking about an act of will. If a force determined to do the unspeakable is met with moral argument but little else, the determined force will win. We have reached the stage at which we have to declare—I look forward to the Foreign Secretary making this clear—that that is a point beyond which we are no longer prepared to go.
