This chapter focuses on the idea of constructive engagement, an umbrella term for mediated and non-mediated forms of communication in which differences can be expressed, respected, and resolved. Hartmut Wessler identifies three ways current scholarship can shift to better address the topic: first, to move from research that emphasizes voice to the practices associated with listening; second, to turn from disruptive conflict toward identifying the potential for integrative conflict; and third, by moving from modes of argumentation to research that examines the “self-transcendent emotions” that fuel constructive interaction with individuals across social divides. Wessler suggests that focusing on constructive engagement can link long-standing concerns articulated by theorists like Habermas focused on rational-critical deliberation with efforts made by social theorists like Georg Simmel, Lewis Coser, and Helmut Dubiel to highlight the integrative and constructive potential of robust but contained conflicts.

Chapter 5 analyzes how the Reagan administration and members of Congress contested US policy toward South Africa’s apartheid regime of institutionalized racial segregation. The chapter examines the administration’s policy of constructive engagement designed to encourage gradual South African reforms through quiet diplomacy while reaffirming US support for the anti-communist and US-friendly regime. Centered on the Congressional Black Caucus (CBC), the chapter then traces congressional efforts to impose various economic measures against South Africa. It demonstrates how members of Congress collaborated with the wider anti-apartheid movement through participation in protests, staged arrests, and the creation of the Free South Africa Movement. Crucially, members of Congress sought to change US policy through the imposition of economic sanctions through legislation. Tracing the legislative battles over sanctions, the chapter shows how a growing congressional coalition, spearheaded by the CBC, framed apartheid as a human rights issue. Under increasing political pressure to distance themselves from apartheid and constructive engagement, moderate Republicans came to favor sanctions, leading to the imposition of the Comprehensive Anti-Apartheid Act in 1986 overriding a presidential veto. The chapter argues that framing of apartheid as a human rights issue contributed to the successful imposition of sanctions.
