My hon. Friend has made a really important point. It is incredibly important that we mobilise all countries in the region, and Turkey is primary among them. We need to learn the whole lesson—namely that there can be no solution without our engaging not just the people of Iraq and an inclusive Government in Iraq, but the wider neighbourhood.
Let me now turn to my fifth criterion. There must be broad support in the region for reasons of legitimacy—because this action must not be seen as some new form of imperialism—and of effectiveness, because regional support is essential to the long-term success of the mission. At the end of August, the Arab League made a statement calling for comprehensive measures to combat ISIL, and we now see a regional coalition consisting of Jordan, the United Arab Emirates, Bahrain and Saudi Arabia and Qatar, as well as other countries.
Sixthly and finally, the proposed action must be proportionate. We must make sure that innocent civilians are protected. I know that strict conditions are in place to ensure that there is proper targeting, and that everything possible is done to avoid civilian casualties.
Having scrutinised those six conditions—just cause, last resort, legal base, reasonable prospects, regional support and proportionality—I believe that they are met.
