Tensions are high in Lebanon, where sectarian clashes linked to the conflict in Syria have erupted. Deutsche Welle spoke to Rouzbeh Parsi from the EU Institute for Security Studies in Paris about the implications of the violence. Rouzbeh Parsi is a Research Fellow at the European Union Institute for Security Studies in Paris where he focuses on Iran, Iraq and the Persian Gulf. DW: Sectarian violence between Sunnis and Alawites, who support Syria\'s president Bashar Assad, has spread from the northern Lebanese city of Tripoli to the capital Beirut, sparking concern that the conflict in neighbouring Syria has spilled over into Lebanon. How are the two conflicts related? Rouzbeh Parsi: You have to remember that though we\'ve had almost 100 years of separation between Syria and Lebanon, they both belong in a sense to the same entity. The connections between these two states and societies are manifold. So that means that whatever happens in one tends to have repercussions on the other. In the case of Syria, because of its relative strength vis-à-vis Lebanon, it\'s always been that the Syrian government, particularly under Assad - his father more than him, but he as well - has been trying to influence and be the primary mover of politics in Lebanon. You can see that in how the Syrians just like everyone else meddled in Lebanon during the civil war. DW: They were present there for almost 30 years during the Syrian occupation of Lebanon. RP: Yes that\'s right. The thing about Lebanon is that it has what you could call structural fault lines that have been there from the very beginning and that no one has really dared or been able to really deal with. To put it in simple terms: they have a constitution from the 1920s that is confessional. It means that they divide the political system according to which religious or ethnic group you belong to. That division is based on a census made in the early 1930s. Since then, there has been no official census in Lebanon. DW:You say there\'s been a little bit of fixing here and there, but never getting to the root of the matter. Are you saying then that the cause of the problem is that the whole constitutional system needs to be revamped since it\'s so antiquated? RP: This is the same problem you have in Iraq, though there, it\'s much fresher. You have a country that is divided more along almost if you will tribal or other kinds of lines. It\'s not the thing that we think of in a democracy, that everyone is their own individual. Think: this is the 1930s. So what you do is you\'re hoping for the moment to be able to get everyone to get along by using their group identities as a way of dividing the spoils of the state so that everyone gets a bit. What was then perhaps a temporary solution gets cemented. Instead of temporarily giving everyone something according to their ethnic group and then slowly making them all citizens that are supposed to make their decisions on the basis of some other idea of politics than kinship. It rather cements it because now you know what you can get is dependent on which ethnic group you belong to. DW: And this of course causes these tensions between the various sectarian parties. RP: I\'m not trying to say that just because of this lacuna in trying to do something, that\'s the reason why everything flares up. I\'m just saying that this thing is underlying and it\'s a potential fissure that can be used. This is a country where different parts of the cities belong to different ethnic or religious groups. Because you have an army that no one really trusts, and has not been able to enforce its authority throughout the country, precisely because during the civil war it broke down and everyone went along kinship lines. It means everyone still has ideas of having their own militia to make sure they survive. DW: So sectarian tensions have always been a part of Lebanon\'s history and the country appears to anyway be a powder keg waiting to explode. Is the conflict in Syria just the spark it needs? RP: I think that would be going too far. I think there have been positive tendencies in Lebanon. The problem is that Lebanon is not isolated from its surroundings. It\'s not as if once they all finally decide to really patch things up and try and redo things - which they haven\'t agreed on - but if they were to do that, everyone else would leave them alone. That\'s the problem with countries like Lebanon. If you take the 1980s, for example, you could see that Iraq and Syria because of their enmity and because of Syria\'s alliance with Iran would play out some of that in Lebanon. But since they didn\'t want to start a war with each other formally, with their own standing armies, they played it out using different groups in Lebanon. In the long run, of course, it just means that a country gets more screwed up. What\'s happening now is that the conflict in Syria is spilling over, both in terms of the fact that the border is porous and there are different groups in Lebanon cheering for different sides in Syria - and the fact that the Syrian government wants to give the impression that they are the only ones who can guarantee normality and stability in the region. So in that sense it works to their advantage that everyone starts getting worried about Lebanon. DW: On an official level, Lebanon has kept a fairly low profile since the conflict in Syria began 14 months ago. What is the government of prime minister Najib Mikati\'s official position on the conflict in Syria? RP: From what I\'ve seen and read, I think they\'re trying not to give any impression that they\'re either meddling or even interested in getting involved. DW: What role is Hezbollah playing here? Their leader Sheik Hassan Nasrallah did call for calm in Lebanon in a televised address earlier this week, but Hezbollah is after all the most powerful force in Lebanon, at least on a military level. RP: Absolutely, and I think not just on a military level but also in organisational structure in general. It probably would beat everyone else, including the state, when it comes to social services and what not. In a sense, if you were to just remove all the labels and ask, who there could actually function as a state, control and run the state more or less efficiently, it would be them. They are trying to stay low simply because this is not the fight that they want to get involved in - neither the one inside Lebanon, nor in the general discussion about Syria. Because on the one hand, they are closely linked to the Syrian government, and at the same time, part of their ideology and rhetoric is about the fact that they are supposed to be defenders of the repressed. So that doesn\'t really work because the people that are being repressed are the Syrians who are against the government that they are allied to. They\'ve tried to hedge their bets a bit, not going all out for the Syrian government and at the same time not blanket condemning everyone else. DW: So where do you see this heading? Russia\'s foreign minister Sergei Lavrov warned on Wednesday that there was a tangible threat of the Syrian uprising spilling over to Lebanon. Do you think there is a risk of this blowing up into a civil war in Lebanon? RP: I would hope and I would not think that is that probable. I think if someone wants it to go in that direction, they have material to play with. But to take it from that low configuration on a local level between two parts of a city, like in northern Lebanon, to make it into an all-out civil war-like situation, that requires some conscious work on someone\'s part and everyone else is dragged along or plays along. But we\'re not there yet. DW: With respect to the current situation in Lebanon, what implications do you see for regional stability, or rather instability? RP: The US assistant secretary of state for Near Eastern affairs, Jeffrey Feltman, was recently in Lebanon - at the same time as the Iranian first vice-president. Both are playing the same game. The Iranians are supportive of the present government because it\'s dominated by Hezbollah and its allies and are promising contracts in energy and so on. The Americans do the same, but under the precondition that Hezbollah and the others stay out of it. DW: So everyone has a horse that they bet on in the Lebanese context. I don\'t think any one of them wants this to escalate. So they\'re not in it for that. But they are part of the game of politics in Lebanon. RP: If what\'s happening in northern Lebanon really becomes something that is happening in Beirut, then the risk of Hezbollah being dragged into it is much larger. If someone were to come to their doorstep in the suburbs of Beirut that are very distinctly Shiite, then of course they will be compelled to react. And then, you never know. But I think for that to happen, it needs some more conscious fueling if you will. So we can just hope that no one is stupid enough to try that.
