Introduction
National interest serves as the fundamental bedrock of foreign policy, rooted in the sovereign state's social contract and fiduciary duty to safeguard the security, prosperity, and survival of its citizens. However, when realpolitik divorces state action from moral constraints, an unbridled pursuit of state advantage risks transforming international relations into an ethical vacuum, eroding international justice and degrading basic human dignity.
The Indispensable Nature of National Interest
Every sovereign government holds a primary obligation to its citizens. In classical realist thought, as articulated by Hans Morgenthau, states operate in an anarchic international system where survival dictates power accumulation and self-help. Foreign policy without national interest lacks democratic legitimacy and accountability to the domestic population it represents.
Erosion of Global Justice
- Compromised Distributive Justice: Vaccine hoarding and nationalism during global pandemics demonstrated how wealthy states prioritized excess domestic reserves over vulnerable populations in developing regions, aggravating systemic global inequality.
- Climate Inaction and Inequity: Major historical carbon emitters dragging their feet on loss-and-damage climate finance illustrate narrow domestic economic priorities undermining intergenerational and international climate justice.
- Unilateral Economic Coercion: Broad, unilateral financial sanctions often fail to alter the behaviour of targeted regimes while weaponizing basic economic access, disproportionately harming vulnerable civilian populations.
Undermining Human Dignity and International Norms
- Violation of the Kantian Imperative: Treating civilian populations in geopolitical proxy wars and conflict zones as collateral violates Immanuel Kant's categorical imperative to treat human dignity as an end in itself, never merely as a means to strategic ends.
- Subversion of Refugee Protections: Arbitrary pushbacks and deportations of asylum seekers at borders undermine the customary international legal norm of non-refoulement, elevating territorial sovereignty over inviolable human rights.
- Humanitarian Crises in Active Conflicts: The prioritization of territorial conquest or decisive military dominance in conflicts such as Ukraine and Gaza leads to the destruction of vital civilian infrastructure, denying basic rights to life and shelter.
Bridging Realism and Cosmopolitan Ethics
Statesmanship requires transitioning from narrow, zero-sum realpolitik to enlightened self-interest. Since transnational threats like climate catastrophe, pandemics, and terrorism ignore sovereign borders, preserving domestic well-being inherently necessitates global cooperation. Adopting philosophical frameworks such as Vasudhaiva Kutumbakam (the world is one family) allows states to anchor foreign policy in ethical multilateralism, collective security, and shared global commons.
Conclusion
While sovereign survival remains a primary duty of the state, foreign policy devoid of ethical accountability reduces international order to raw coercion. Sustainable global peace requires aligning domestic interests with cosmopolitan solidarity, ensuring that statecraft respects shared human dignity and global justice.
