Which theoretical approach would explain the friendly relations between the United States and Britain based on mutual interests and shared norms?

The correct rationale for the preference towards liberalism in explaining the friendly relations between the United States and Britain lies in its emphasis on mutual interests, interdependence, and shared values.

Liberalism posits that cooperation between states is not only possible but beneficial, given that states often pursue common goals and have overlapping values. The strong historical ties between the U.S. and Britain, grounded in democratic principles, shared cultural heritage, and aligned economic interests, align perfectly with this perspective. These elements foster collaboration on multiple fronts, such as trade agreements, security partnerships, and common stances in international organizations.

This approach also highlights the role of international institutions and norms in facilitating cooperation, which further contributes to the understanding of the friendly relations between the two countries. By focusing on the importance of shared beliefs and the potential for collective action, liberalism effectively captures the essence of U.S.-Britain relations.
