Paddy Ashdown says it's OK. I supported the Nato intervention in Libya. As British MPs meet to consider whether the country should actively join the US and other nations in bombing the outfit that calls itself "The Islamic State", and which I still refer to as "Isis", this should be quite straightforward. But I have deep misgivings.
There are enough reasons why such action should be supported. Firstly Isis are evil. They represent a particular sort of totalitarianism that I detest, casually terminating the lives of anybody that gets in its way. Its attempt to appropriate the religion of Islam is as contemptible as the Ku Klux Klan's similar appropriation of Christianity.
Secondly the action is legal under international law, provided that it stays within the boundaries of the Iraqi state, since the Iraqi government has requested it. Having said that I set less store by the norms of international law in such matters than many. It concedes too much power to sovereignty of national governments, and to the veto of UN Security Council members.
Thirdly, there is some level of direct threat. Isis has said that it wants to carry its crazy war into developed nations, including ours, through random acts of violence. It will kill any of our non-Muslim citizens that it can lay its hands on. Having said which it has not put much organisational effort into intervention in Western countries - being more interested in carving out its own statelet in Greater Syria.
I place some weight to showing solidarity with the USA. The Western powers are stronger if they act together, and we do have a very strong common interest. Still, the world view of many American politicians is ignorant nonsense, and we should not be too tied to them.
I find that my unease reflects a rather similar attitude with many on the political right to domestic politics. Actions driven by a bleeding heart or anger can so often lead to the opposite of what we intend.
The first problem is dependency. The interventions by the USA and its allies in Iraq have led to an expectation that the Western powers will intervene to sort out any nasty problem in any neighbourhood (outside Russia, China or India, anyway). So the locals lose any incentive to sort out problems for themselves. We have seen this with Afghan government of Hamid Khazai. We have seen it with post Saddam governments in Iraq. They use the US security umbrella to carve out their own corrupt polities without any regard to their country's long term future. They governments don't even act as loyal allies.
The whole Isis mess was created by the failure of two governments: those of Syria and Iraq, drawing on the support of Iran and the Lebanese faction of Hezbollah. Their ineptitude created a political vacuum which Isis has exploited. They have shown themselves incapable and unfit to rule the areas that Isis now controls. But we have no other party to back, beyond the nascent Kurdish state. The US has wrought concessions from the Iraqi state, but I can't see how these will be enough to regain the trust of the Sunni tribes. Past experience shows that as soon as US pressure is withdrawn, the Iraqi government reverts to type.
A further problem is lack of proximity. I firmly believe that the closer we as a country are to another, the more prepared we should be to intervene in its affairs. This is not just a matter of physical proximity, but also cultural. The Falkland Islands were (and are) close to Britain in that sense. Iraq and Syria are a long way off. I feel happier about our country intervening in Kosovo and Bosnia and, perhaps, Sierra Leone. If Turkey, which is on the edge of being a European nation, and is part of Nato, had chosen to involve itself in this affair, then perhaps we could make a case for helping its defence. But Turkey is staying firmly neutral.
I am not persuaded that this country's participation in the 2003 gives us any obligation to help sort the mess out. I think responsibility for the mess lies with the Iraqi and Syrian governments. Neither is the presence of British volunteers amongst Isis's ranks - though we should takes steps to reduce the flow of such people. However, I do think that our past involvement points towards humanitarian and economic assistance now.
And another thing. I am deeply uncomfortable with the idea that air power (including the use of drones) is some kind of morally clean way of involving ourselves in a conflict. It may put fewer of our servicemen's lives at risk, but the death and destruction that they deal out is as real as anything that an infantryman does. And it leaves unanswered the question of who controls the ground after Isis has been beaten.
The world has a problem with failed states and power vacuums. This is what Isis exploited in Syria and Iraq. We also have Somalia, Libya and many other parts of the African continent. Post-imperial occupation by foreign powers has not proved a robust solution. Neither does the projection of Nato military might, outside Europe, anyway.
We need to find a better way. This needs to be led by the local powers, with perhaps further support as required through the UN. In the case of Iraq-Syria these local powers are Turkey, Iran and the Gulf Arab states. These powers somehow need to work out a new political settlement for the region, which, in my view, will require the redrawing of international boundaries. That Iran and Saudi Arabia have behaved in a highly irresponsible manner to date does not mean we can avoid making them part of the solution.
Perhaps President Obama's coalition will help bring about such a resolution; he at least grasps the limits of military power better then most - though he is buffeted by the winds of US domestic politics. I would need to be convinced that this is so before endorsing any further British military intervention.
