Let me start by saying how pleased I am that Keith Vaz has brought forward this debate, and how pleased I am to participate in it and follow what he has said. I think we all agreed with his feelings, which he set out very clearly and quite emotionally in his speech, for the people of Yemen, who have suffered so tremendously. I thought his description of that was very powerful indeed. I may be only the fourth speaker in this debate, but the three speeches before mine have covered so much of the ground and so many of the points that there are only a few additional points I want to comment on.
First, I think it is a cause for celebration that we do have the outlines of a truce. We should take great comfort from that. I know it is just the outlines and that it could always go further than that, but in this sort of conflict one has to grab whatever one can to try to keep some sanity in the whole process. The peace process is now more akin to a mediation than to a conference set up to tell the Yemenis what to do. In any mediation, the system only works if there are two people who are genuinely prepared to sit down and talk to each other. Only then can the essence of a mediation, which is for the participants to agree and to bring out themselves the solution to the problem, actually come through. That is a very important point to bear in mind, including for the role the UK may want to play.
A lot more work needs to be done on the triggers that can bring two warring sides to the realisation that they need to come together to agree a peace. I do not think we have done enough work on that internationally. We have done a lot of work on conferences that can take place to cover these issues, but I do not think that they are as important as trying to get the people themselves to agree. The triggers may be very different for different conflicts. The trigger may be the crisis of hunger in the country. The triggers may be external, such as stopping arms sales, in which case we need to stop arms sales to both parties. There may be a whole range of things that we need to look at to make sure that we can really get to grips with this.
It is worth remembering that this whole war started as a result of a Houthi rebel insurgency. I know that some speakers have particularly said that they need to condemn and we all need to condemn the faults on both sides. However, the Houthis are a very unsavoury group of people. Stephen Twigg raised the issue of boy soldiers. Whether the Saudis are also generating boy soldiers is a separate issue, but we know that the Houthis are employing boy soldiers, and that has to stop because it is a great attack on everything that we all believe in. We must bear in mind that they killed Saleh, the former Prime Minister, and the hon. Gentleman has already mentioned landmines as well.
