Beyond Westphalia: Rethinking Sovereignty In The Twenty-First Century – Analysis

Key Takeaways:

• The traditional Westphalian model of sovereignty—territorial control, sovereign equality, and non-intervention—faces growing challenges from globalization, cyber warfare, drones, and non-state actors.
• The 2025–2026 Iran–Israel conflict illustrates these pressures through direct missile and drone strikes, proxy involvement, and cyber operations that blur borders and complicate responsibility under international law.
• Despite these strains, sovereignty has not disappeared; states still invoke it to justify actions, and it continues to evolve as a flexible, multi-layered concept rather than an outdated ideal.

Introduction 

The principle of sovereign was used to frame the structure of International system of International politics since the 1648 in Westphalia, this system stated that there is absolute authority of a state within the territorial boundaries, which cannot be interfered by the other state from external domain of political, economic and Social and such factors and norms like territorial Integrity of state , sovereign equality of states, non-intervention etc emerged as important principles for the state in conduct and transaction amongst them, and these norms also framed in the United Nation’s Charter, till recently. 

In recent decades, however, academic scholars have come to challenge if our understanding of sovereignty still reflects reality in ever changing global environment. Globalization, technological innovation, international organizations, cyber war, terrorism, and transnational conflict made it increasingly hard to draw a line between the domestic and the international realm. Conflicts today are seldom contained within borders, and governmental actors are not the only actors to exercise political authority anymore. 

Such changes have raised questions about the end of Westphalian sovereignty and about its transformation. 

By examining the recent conflict between Iran and Israel from 2025 to 2026 we are given an excellent example of these debates. Whereas past tensions have been characterized by indirect engagement, the war involved direct missile attacks, drone attacks, cyber warfare, and the deployment of proxy elements of various regional states and non-state actors, all of which strained the concepts of borders, state power and limits of military conflict. This article will argue that the conflict does not bring an end to the sovereignty of Westphalian state, but rather show how it continues to be the primary feature of international politics and can be regarded as flexible, debated, and responsive to contemporary realities.

Westphalia: More Than a Historical Treaty

The Peace of Westphalia, signed in 1648, brought the Thirty Years’ War to a close, and it is typically regarded as the dawn of the modern sovereign state system. While scholars can debate whether the Treaties in and of themselves ushered in a system based on a system of fully sovereign states, the peace undoubtedly represents a significant juncture in the development of the international system. Sovereignty in a Westphalian framework rest upon three pillars: territorial sovereignty, which holds that a government has the exclusive control over a state’s borders; sovereign equality, according to which states are equal in their international standing, regardless of their size or influence; and non-intervention, the principle that one state should not interfere in the internal affairs of another. 

Taken together these concepts enshrined the state as the central unit in the international system. 

However, the standard narrative regarding the implications of Westphalia for modern sovereignty have faced several criticisms, as discussed by Steve Smith, Brian Schmidt, and Stephen D. Krasner. The argument that there was never really sovereign state as an “ideal type” has been made by Krasner, arguing that, the idea that there has been much state sovereignty as theorized has always been a simplification for even if we consider some instances to be sovereign it has seldom been in the manner set forth by ideal theory due to the fact that stronger actors often have a need for interventions to address strategic threats, and to the degree that intervention is an infringement upon some dimension of sovereignty it cannot be asserted that the sovereign state was a fully formed ideal at 1648 as some interpretations of Westphalia are to interpret. Andreas Osiander goes so far as to claim that 1648 actually did not create fully sovereign states in an international context at all and argues that a modern notion of Westphalia has really emerged more recently and represents in some regards more of a political myth than a reality of 1648, that scholars imposed modern meaning to the Treaties to serve their purpose. 

While these points should not lead to a disavowal of the concept of sovereignty altogether, they point to the fact that this form of sovereignty has been continuously negotiated, shaped by power, diplomacy and particular historical circumstances. 

In understanding the nuances of the system’s historical origins, we are prevented from considering the issues that arise in sovereignty today as wholly novel and unexampled.

Iran–Israel and the Limits of Sovereignty

The recent escalation between Iran and Israel highlights the emerging problems for the Westphalian model. Until now the conflicts had been played out indirectly through a mix of espionage, sanctions, proxies, and limited intelligence operations. However, with both sides exchanging missiles and drones, deploying cyber-attacks, and launching border raids this is a serious interstate dispute in the Middle East today. 

Geographical borders are proving much more vulnerable now to military action than ever before. 

The availability of technology like precision missiles, drone warfare and sophisticated intelligence networks means that territorial occupation is no longer the only tool available to a state in projecting its power. It is no longer necessary for states to march into territory to wield influence through force and even through cyber-attacks state power can cross borders. This new form of conflict also shows the increasingly important role played by proxies. State like Hezbollah, Houthis and the numerous militias in Iraq and Syria play a vital role in state system. 

Though these non-state actors do not have the formal sovereignty of state they wield significant military and political power and play an increasingly central role in regional affairs. 

Their ability to shape interstate relation blurs the lines between interstate and intra state warfare, posing many questions about responsibility and culpability. Geopolitical competition is the other factor at work. We can’t simply interpret the current state’s actions in terms of an Iran- Israel conflict. Instead, it’s part of broader regional competition involving the Gulf states, the US, and complex relationships in regional security arena. As an action by one state causes ripple effect for others, sovereignty seems to be exercised in a connected region not in isolation. Even though, these are challenges sovereignty remains important. 

Both sides invoke national security and sovereign rights in justifying their actions and even when acting against the spirit of non-intervention, both Iran and Israel invoke the principle of sovereignty in the justification of those actions. 

Law, Power and New Forms of Sovereignty

The Iran-Israel conflict is also revealing of the strained relationship between sovereignty and international law. On the one hand, Article 2(4) of the UN Charter forbids attacking other countries’ territorial integrity and territorial integrity and, on the other, Article 51 protects sovereignty, as it asserts states’ inherent right to self-defence. But both article’s interpretations have become more disputed over time. Iran and Israel can use self-defence to justify at least some of their military actions and contemporary security threats like rocket attacks, proxy organizations or cross-border terrorism made new interpretations to anticipatory self-defence and to the proportionality requirements. 

Christine Gray stated the law for use of force to use of force became so complicated, because conflicts in today involves non-state- actors and “new ways to use of war” not foreseen by traditional international law framework. At the same time, the concept of sovereignty has moved further than its basic conception as territorial command over the population in a given territory, and states have gained power and authority through diplomacy, economic means, security cooperation, intelligence sharing, or technical skills. Non-state- actors and organizations have also become relevant for determining political outcomes in the system and, therefore, sovereignty is a multi- layered concept today, where power and authority are shared among various actors and levels of government. However, the idea of sovereignty still matters, only to be shaped by new forms of sovereignty.

Conclusion

The Iran-Israel crisis offers an invaluable moment to re-examine how we define sovereignty in the 21st Century. The various manifestations of conflict – whether conventional direct assaults, proxy attacks, legal entanglements or cyber warfare – defy the classic Westphalian definition of state sovereignty. But none of these suggest the demise of sovereignty, far from it. Instead, sovereignty has evolved as it has transformed international political relations as we know them, as the key actors in world affairs remain the nation-state and, while that holds true for the Iran-Israel crisis it is also true for any nation state in any circumstance, although today this includes a whole host of players.
