Why the Israel-Iran Conflict Matters Globally
Ali Saeed
Islamabad: The Israel–Iran conflict remains one of the most consequential and enduring security challenges in the Middle East.
What began as a political and ideological rivalry has evolved into a multidimensional confrontation involving military strikes, proxy warfare, nuclear concerns, diplomatic tensions, and emerging technological risks.
In 2026, this conflict continues to shape regional stability and influence broader global security discussions, with developments in Lebanon, Syria, Gaza, and the Persian Gulf demonstrating its far-reaching consequences.
The roots of the conflict can be traced back to the 1979 Iranian Revolution. Following the revolution, Iran severed diplomatic relations with Israel on February 18, 1979, and adopted an openly hostile stance toward the Israeli state.
Since then, Tehran has opposed Israel politically and strategically, while Israel has viewed Iran’s nuclear ambitions, ballistic missile programs, and regional alliances as significant threats to its national security.
Over time, the rivalry expanded through Iran’s support for groups such as Hezbollah and Hamas, creating a persistent regional security dilemma that extends far beyond the borders of both countries.
For decades, particularly from the mid-1980s onward, the confrontation largely remained indirect. Syria, Lebanon, and Gaza became key arenas for proxy competition, where both sides pursued strategic objectives without engaging in full-scale direct warfare.
Israeli airstrikes against Iranian-linked targets and the activities of Iran-backed groups sustained a continuous cycle of confrontation while keeping the conflict below the threshold of open war. However, developments between 2023 and 2026 pushed the rivalry into a significantly more dangerous phase.

Hezbollah entered the conflict along Israel’s northern border the following day, heightening fears of a wider regional confrontation. In November 2023, attacks by the Iran-backed Houthi movement in the Red Sea expanded the crisis further by threatening vital international maritime routes.
These developments transformed what initially appeared to be a localized conflict into a broader regional security challenge with international implications.
Tensions escalated further in April 2024 when Iran accused Israel of killing two Iranian generals in Syria. In response, Iran launched a large-scale aerial assault on April 14, marking one of the most direct military confrontations between the two states in recent history.
Additional escalation followed in July 2024 after Hezbollah-linked rocket attacks in the Golan Heights and Israel’s killing of a senior Hamas leader in Iran. These incidents reinforced concerns that the region was moving closer to direct war.
Throughout 2024 and 2025, missile and drone exchanges became increasingly frequent. Israel continued targeting Iranian-linked military assets and infrastructure, particularly in Syria, while Iran and its allies sought to increase pressure on Israeli interests across the region.
The conflict reached a critical point during the Twelve-Day War in June 2025, when Israeli forces launched extensive strikes against Iranian nuclear facilities, military installations, and strategic infrastructure.
The fighting intensified through sustained aerial and missile attacks before a ceasefire was eventually achieved.
The June 2025 escalation highlighted the increasingly direct nature of the confrontation. Israel launched a surprise air campaign on June 13, followed by attacks on energy-related infrastructure on June 14.
Heavy exchanges continued on June 15, affecting key locations such as Haifa’s oil refinery and the Weizmann Institute. On June 16, Israeli operations expanded to target Iranian military and media facilities, while the United States repositioned forces throughout the region.
By June 17 and 18, international attention had shifted toward Iran’s Fordow nuclear facility and the possibility of further escalation involving senior political and military leadership. Evacuation warnings near Iran’s Arak nuclear facility on June 19 further underscored the seriousness of the crisis.
Another major turning point occurred in February 2026 following the collapse of US–Iran negotiations. Coordinated Israeli and American strikes targeted Iranian facilities, prompting missile and drone retaliation from Iran.
The resulting attacks damaged civilian and infrastructure targets and renewed concerns that the conflict could evolve into a broader regional war involving multiple actors.
Despite the ceasefire reached between Israel and Hezbollah in late 2024, tensions along Israel’s northern border remain volatile. Israeli military operations in southern Lebanon have continued against groups considered security threats.

Iran’s nuclear program remains at the center of the conflict. Israeli strikes in 2025 targeted key nuclear facilities and senior military leadership, causing significant damage to infrastructure and slowing enrichment activities.
Supporters argued that these operations were necessary to address urgent security concerns, while critics maintained that military action alone could not provide a lasting solution to the challenges posed by Iran’s nuclear capabilities.
Although diplomatic efforts continue, they remain fragile and uncertain. Following the Twelve-Day War, US–Iran negotiations resumed in Muscat, Oman, in early 2026 and were described as a positive step toward limiting nuclear escalation.
However, major disagreements persist. Maritime tensions, including reports of a US interception of an Iranian drone near the USS Abraham Lincoln, demonstrate how quickly diplomatic progress can be undermined by security incidents.
Iran’s demands regarding limits on the US military presence in the region have added further complexity to negotiations.
The conflict has also influenced domestic political debates in the United States. Public opinion and electoral discussions increasingly reflect differing views on the extent of American involvement in Middle Eastern conflicts.
Some political figures have reduced engagement with traditional pro-Israel lobbying networks, while others continue to advocate strong strategic cooperation. Despite these debates, maintaining Israel’s Qualitative Military Edge (QME) remains a central pillar of US policy.
Recent proposals under the National Defense Authorization Act (NDAA) and the Israel Assistance Act (IAA) seek to deepen defense, intelligence, and technological cooperation between the United States and Israel. Supporters argue that such measures enhance regional security and strengthen defense coordination.
Critics, however, contend that they may reduce policy flexibility and deepen long-term commitments without sufficient oversight. Another notable development is the growing transformation of military aid into long-term defense and technology partnerships between American and Israeli firms, reflecting a shift toward more institutionalized forms of cooperation.

Analysts are examining questions related to regional leadership, the strategic importance of the Strait of Hormuz, and the increasing role of artificial intelligence in military targeting and decision-making.
The growing use of autonomous systems has raised important concerns regarding accountability, transparency, and the regulation of emerging military technologies.
At the international level, the expiration of the New START Treaty has intensified concerns about the future of arms control and global nuclear stability.
At the same time, evolving deterrence strategies, shifts from the US National Security Strategy (NSS) to the National Defense Strategy (NDS), and changing geopolitical alignments such as expanding EU–India cooperation demonstrate that the Israel–Iran conflict exists within a much broader and increasingly complex security environment.
An often-overlooked aspect of modern warfare is the vulnerability of chemical and industrial infrastructure. The Chemical Weapons Convention (CWC), implemented through the Organisation for the Prohibition of Chemical Weapons (OPCW), remains the most comprehensive international framework prohibiting the development, production, stockpiling, and use of chemical weapons.
However, while the convention effectively addresses chemical weapons themselves, it offers limited protection for petrochemical and industrial facilities targeted during conventional conflicts. Damage to such facilities can release hazardous substances into the environment, creating serious humanitarian, environmental, and public health risks while complicating emergency response efforts.
In my view, the Israel–Iran conflict can no longer be understood solely through the lens of military confrontation. It has become a multidimensional challenge involving security, diplomacy, technology, energy, arms control, and international governance.
As military tensions, nuclear concerns, technological developments, and diplomatic uncertainties continue to intersect, the conflict remains one of the defining issues in contemporary international relations.
Its future trajectory will not only influence stability in the Middle East but will also shape broader debates on deterrence, diplomacy, arms control, conflict management, and the governance of emerging technologies.
Whether through confrontation or negotiation, the decisions made by regional and global actors in the coming years will have consequences far beyond the immediate battlefield.
