In the age of governance, political leadership is a multi-level activity. Multi-level governance research shows that policy-making at national, transnational, and subnational levels of governance is increasingly tangled, interconnected, and overlapping. Political leadership research has mainly focused on how politicians perform political leadership at a single level of governance, however. Chapter 8 develops a concept of multi-level political leadership, which aims to capture how political leadership involves efforts to affect decisions made by politicians appointed at other levels of governance. The conditions and opportunities for performing multi-level political leadership vary between politicians authorized at transnational, national, and subnational levels of governance. Community sentiments are not equally strong among all citizens; politicians at different levels do not have the same type and amount of NATO resources; public attention varies; and the impact and influence that national, transnational and sub-national politicians are expected to have differ. In light of these differences, expectations are that transnational and subnational politicians are more likely to embrace a multi-level leadership approach than national politicians will.
