In the Hope That the US–Israel–Iran War Won’t Become Endless: Lessons from Wars That Finally Found Resolution

By Karl Garcia


As the conflict involving the United States, Israel, and Iran escalates in early 2026, fears of a protracted, open-ended war are spreading far beyond the Middle East. Following coordinated U.S. and Israeli strikes on Iran, including attacks on nuclear and military infrastructure, and the reported death of Iran’s Supreme Leader, retaliatory missile and drone attacks have extended beyond Iran’s borders into Lebanon and Gulf states, involving Hezbollah in Lebanon, Yemeni Houthi forces, and threatening major trade routes in the Strait of Hormuz. These developments have regionalized the conflict, increasing its complexity and the potential for a long-term, multi-front war. (Global Conflict Tracker)

This moment — fraught, volatile, and reminiscent of past large-scale wars — raises a pressing question: Can such a war ever end, or are we witnessing the birth of an “endless war?” History shows that wars between powerful states and long-standing adversaries can be resolved, but only with sustained diplomacy, structural reform, and decades of societal transformation. Examining past conflicts that finally concluded offers both caution and guidance.


Lessons from Historical “Endless Wars”

Endless wars are not only defined by duration, but by cyclical violence, failed military solutions, and profound societal costs. Across the globe, some of the most protracted conflicts have eventually reached closure, often through negotiation and reform rather than military victory alone.

Colombia’s FARC Insurgency (1964–2016)

Colombia’s conflict with the Revolutionary Armed Forces of Colombia (FARC) lasted more than five decades, fueled by rural inequality, ideological insurgency, and narcotics trafficking. Only in 2016 did the Colombian government and FARC sign a comprehensive peace agreement, disarming combatants and integrating former rebels into political life, while addressing rural reforms.

Lesson: Transforming an insurgency into political discourse and structural reforms can end violence that military force alone could not.

Philippine–Moro Conflict (1970s–2019)

The Moro Islamic Liberation Front (MILF) fought for autonomy in Mindanao for decades. Through prolonged negotiation, the Bangsamoro Organic Law and the creation of the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM) in 2019 addressed core grievances over governance and identity.

Lesson: Autonomy and political recognition can convert prolonged conflicts into peaceful administrative frameworks.

Nepalese Civil War (1996–2015)

Nepal’s Maoist insurgency fought the government for a decade. While combat ended with the 2006 peace agreement, full political integration and constitutional reform took until 2015, transitioning Nepal from monarchy to a federal democratic republic.

Lesson: Ending combat requires structural political reform; post-war reconciliation is often a lengthy process.

Sudan – Darfur & Eastern Conflicts (2003–2020)

Cycles of violence in Sudan persisted for nearly two decades. The 2020 peace agreements between the transitional government and multiple rebel groups formalized recognition, civilian inclusion, and reconstruction.

Lesson: Inclusive political settlements for multi-faction conflicts can formalize peace, though implementation remains challenging.

Sri Lankan Civil War (1983–2009)

The LTTE insurgency was decisively defeated militarily in 2009. However, decades-long reconciliation and reintegration were essential to stabilize affected regions.

Lesson: Even military victory must be paired with social reconciliation to prevent recurrence.


Comparative Timeline of Wars That Found Resolution

ConflictDurationTurning Point / ResolutionKey Lessons
Colombian FARC Insurgency1964–2016 (~52 yrs)2016 peace agreement: disarmament, political integration, rural reformsNegotiation over military victory; structural reforms; long-term commitment
Philippine–Moro Conflict (MILF)1970s–2019 (~40+ yrs)2014 Comprehensive Agreement → BARMM 2019Autonomy and recognition; sustained negotiation
Nepalese Civil War1996–2015 (~19 yrs, 10 yrs active combat + integration)2006 peace agreement + 2015 constitutionStructural political reform; lengthy post-war reconciliation
Sudan – Darfur & Eastern Conflicts2003–2020+ (~17 yrs)2020 peace agreementsInclusive multi-faction settlements; careful implementation required
Sri Lankan Civil War (LTTE)1983–2009 (~26 yrs)2009 military defeat + reconciliationMilitary victory alone is insufficient; social reconciliation crucial
Mali – Tuareg & Islamist Conflicts2012–2015+ (~ongoing cycles)2015 Algiers Peace AccordPeace agreements can reduce conflict but require ongoing governance support

Key Patterns in Ending “Endless” Wars

Across these cases, several patterns emerge:

  1. Negotiation Over Total Victory: Military force rarely delivers lasting peace; settlements with political or structural concessions do.
  2. Addressing Root Causes: Conflicts rooted in identity, governance, or inequality require systemic solutions.
  3. Time and Commitment: Ceasefires and treaties are milestones, not endpoints; implementation takes years or decades.
  4. Multi-Faction Coordination: Inclusive agreements across all parties are necessary to prevent relapse into conflict.

Applying Lessons to the US–Israel–Iran Conflict

The current US–Israel–Iran war differs from these historical cases, but the risk of becoming an endless conflict is pronounced. Decades of hostility, proxy wars, nuclear standoffs, and ideological opposition have already produced regional instability. Importantly, the conflict has spread to Lebanon, Yemen, and Gulf neighbors, involving Hezbollah, Houthi forces, and threatening shipping lanes, signaling a multi-front escalation reminiscent of past long wars. The geographic and political spread increases the stakes and the complexity of any potential resolution.

History teaches that military escalation alone cannot end protracted conflict. Lasting resolution would require:

  • Renewed diplomacy: with clear, enforceable conditions acceptable to all parties.
  • Incentives for de-escalation: economic, political, or security guarantees.
  • Regional and international coordination: ensuring agreements are monitored and upheld.
  • Addressing core grievances: balancing Israel’s security concerns, Iran’s regional influence, and the stakes of proxy actors.

Conclusion: Hope Amid Risk

The historical record offers both warning and hope. Endless wars can end, but only when leaders confront the limits of violence and commit to structural, political, and social solutions. The cases of Colombia, Nepal, the Philippines, Sudan, Sri Lanka, and Mali demonstrate that even the most intractable conflicts may yield to negotiation, compromise, and long-term engagement.

For the US–Israel–Iran conflict — now regionalized across Lebanon, Yemen, and the Gulf — the lessons are clear: avoiding decades of violence will require sustained diplomacy, inclusive solutions, and strategic patience. Without such steps, the world risks watching a conflict escalate into the next “endless war.”
