The continual interference by external actors in Lebanese affairs has created a political environment in Lebanon that has seemingly intertwined domestic and regional/extra-regional politics. This reality has relatively blurred the line between these political domains which often leaves one wondering if Lebanese politics are a distinct phenomenon or simply a reflection of regional/extra-regional developments. Understanding the relationship between domestic and regional/extra-regional politics in Lebanon, particularly how agreements are achieved among numerous actors, has been relatively absent from scholarship. My paper seeks to address this void in two significant ways. Firstly, the overlap between domestic and regional/extra-regional politics has not been properly dealt with by political scientists. To understand the workings of the Lebanese political milieu, the divide between these two disciplines must be bridged. Following a literature review, I will argue for a framework of analysis that eliminates this issue by focusing on the domestic, regional and extra-regional veto players in the Lebanese political milieu. The veto players approach is critical, particularly for Lebanon with its numerous and diverse political players, because it provides one with the ability to focus only on those actors who are necessary for changing the status quo of a particular issue. Secondly, I will analyze the veto players approach regarding Lebanon's foreign policy in two different eras: 1958-1964 and 2005-2010. I want to understand which actors, actions and circumstances are contributing to Lebanon's instability. Are external actors responsible for Lebanon's instability or are domestic actors taking advantage of these external actorsa Who and what is needed to eventually achieve stabilityb Does a gain in Lebanon, reflect a loss in the regionr Answers to these questions will ultimately provide an understanding as to whether Lebanon can play a role in stabilizing the region. This study suggests that the lack of intra-confessional political competition and an increase in the number of external veto players will perpetuate the current intransigence/instability of the Lebanese political system.
