I am delighted to take part in this debate. As my right hon. Friend the Member for Rutland and Melton (Sir Alan Duncan) said, there are no simple solutions to this complex issue. Today’s debate illustrates the complexity that we face as legislators in having to take decisions on behalf of the British people. My right hon. Friend the Prime Minister made a very compelling case. It was an absolutely excellent speech and I agree with every word of it. I have tried to press on him my view that we should have taken this action sooner, but I understand why he could not do so: it is because he was not prepared to bring before the House a motion on which he was not certain of securing a result. I do not blame him for that caution.
The Prime Minister posed the question, “Where is the British national interest?” We need to be satisfied that the British national interest is met by the strategy that he set out. I believe that the answer is crystal clear and that it is in the British national interest that we should support this motion. All the leaders around the world have declared that these IS, ISIL, ISIS people are beyond the pale and are a major threat not just to the middle east but to us here at home. As my hon. Friend the Member for North Devon (Sir Nick Harvey) said, they have already overrun a large part of Iraq. They have threatened to overrun the whole of that country, resorting to their barbaric methods in so doing—methods that we have ruled out and most countries abandoned centuries ago. We have seen, and our constituents have seen, the slaughter of innocent people and the way in which these barbaric people have been behaving. They have seen our own nationals and US nationals murdered as well.
It seems to me therefore that if this threat is so great, we have to address it. There are two clear issues. There is a blurred line between them, it is true, but the imperative today is that we should prevent IS from overrunning the whole of Iraq. Indeed, the objective must be to drive them out of Iraq as far as we possibly can. As the right hon. Member for Holborn and St Pancras (Frank Dobson) so eloquently said, it is not a question of making an act of faith; we have seen it work. The troops on the ground have said that without the intervention of the United States’ air strikes, they would not have been able to blunt the attack of IS in northern Iraq. We know it works. It is not as though we are trying to suggest something for which we have no intimation as to what might happen.
