Conclusions and Outlook
Summarizing the various findings from the empirical chapters, this chapter concludes that party politics does matter for external relations and that democratic politics does not stop at the water’s edge. However, the concluding chapter discusses a number of caveats and qualifications to this general finding: first, party-political contestation over foreign affairs is often less intense than over domestic politics; second, party positions do not simply translate into state policy when parties enter government; third, party positions develop in interaction with external events, especially if parties are in government. Altogether, party politics is best understood as an independent and thus far understudied factor in explanations of foreign policy that interacts with other domestic politics variables, such as a state’s institutional structure, and international ones, such as a state’s international position or exposure to threats. The conclusion closes with suggestions for further research. (Populist) far-right parties and parties in the ‘Global South’ are identified in particular as areas for future research, as both have barely been studied systematically and both are very likely to have an impact on the liberal international order and world politics more broadly.
