The decision to invade Iraq was the most disastrous foreign policy decision taken by this country in my lifetime. It did not cause, but it greatly contributed to, the extraordinary problems that have persisted in the middle east and the wider world ever since. I fear it will continue to have tragic consequences for some years to come.
First, we all owe a debt to Sir John Chilcot for producing what will undoubtedly be the most authoritative analysis of how on earth such an appalling blunder came to be made. I certainly have not had the chance to get much beyond the executive summary and just a little bit of the rest of it. It will take a long time before anybody in this House gets through the millions of words that have been produced. The lessons for the inquiry into the Iraq war will be of benefit in particular to specialists: those in the military, the intelligence service, the diplomatic core and politicians—Ministers, shadow Ministers and those who hold the Government to account—for many years to come. It is too soon to follow up on his extremely formidable findings, which I am sure are correct, but there is a role for this House to begin to consider, as we are, its political aspect.
Sir John Chilcot has examined the formal records, meetings and processes. He analysed them to see what happened, but he is not a politician. The House of Commons and the Ministers involved are able to look at this with a slightly different eye. Why did people reach particular decisions? What is it that makes us want to reach those decisions? Where did it go wrong, in particular as far as the collective system of Cabinet Government is concerned, and the accountability, through Parliament, to the wider public? Because Sir John Chilcot is not a politician, I am not sure that he is able to answer on the wider perspective.
I would like to begin by agreeing with one point made by the hon. Member for Islington South and Finsbury (Emily Thornberry) and say how irrelevant it has been to try to turn all this into a witch hunt against celebrity individuals who were involved at the time. That is one of the great failures of political debate in our day. As far as the wider media and the world were concerned, the recent referendum debate was largely the Dave and Boris show. It is quite pointless to say, “Let’s persecute Tony Blair. He was in charge. Are we going to censure him? Is he going to be prosecuted as a war criminal?” and all the rest of it. That is also true for all the other individuals involved.
The one thing the report makes quite clear is that nobody has committed any crime. As one who was present at the time, I have absolutely no doubt that anybody acted on any other basis than that they believed passionately they were acting in the public interest. One of the great things about Tony Blair was that he did believe passionately in what he was doing at the time. That was very evident on the Floor of the House. He never had a doubt about what he was doing, so I am not surprised that he continues to protest as strongly as he does. He has not changed his mind. He believed he was acting in the national interest in cementing our alliance with the Americans. He thought that was absolutely key to our security. He thought that a British contribution would help the Americans with planning, advocacy and so on. He firmly believed that just removing Saddam Hussein was a virtuous act that would make the world a better place—he still does.
Then, as now, regime change is the point on which he gets most passionate. He really thinks—he is probably right; I agree with him, actually—that he got rid of an evil regime. I agree with those who say that that was not in itself a totally adequate achievement. He certainly believed that the regime had weapons of mass destruction. I faced him in the House, intervening on him and so on. I remember one day thinking, “This is the last man still living who still believes they are going to find weapons of mass destruction in Iraq.” It was increasingly obvious to everyone else that no such material was going to be found. Pursuing Tony Blair is a complete irrelevance to what the House should be looking at .
