The Middle East is currently gripped by a direct military confrontation between Iran and Israel, a conflict that has rapidly escalated from long-standing proxy warfare into overt hostilities.
June 23, 2025: A Day of Intense Action and Growing Concern
Today, June 23, 2025, has been marked by a continuation of the intense exchanges between Iran and Israel, and significant international reactions to the recent U.S. intervention.
- Iranian Retaliation and Threats: Iran has vowed retaliation for the U.S. strikes on its nuclear facilities, which occurred yesterday.
While no explicit direct retaliation against the U.S. has been reported as of late Monday, the Islamic Revolutionary Guard Corps (IRGC) has warned the United States to “expect regrettable responses,” implicitly threatening U.S. bases in the region.
Iranian media has reported the shooting down of an Israeli Hermes 900 drone by IRGC forces in Khorramabad, Lorestan province. Furthermore, in a significant move, Iran’s parliament conditionally approved a measure to close the Strait of Hormuz, a critical global oil transit chokepoint, pending final approval from the Supreme National Security Council. Iranian President Masoud Pezeshkian joined a protest in Tehran condemning the U.S. and Israeli actions.
- Continued Israeli Strikes: Israel has pressed on with its air campaign against Iran. Reports indicate Israeli airstrikes on an IRGC division headquarters in Tabriz and a strategic missile base near Yazd City, which reportedly housed long-range Khorramshahr ballistic missiles in underground tunnels.
The IDF also claimed to have struck Khorramshahr-4 missiles in Iran before their launch today. An Israeli missile was also intercepted heading towards Eilat.
- U.S. Stance and Diplomatic Moves: U.S. President Donald Trump, who departed the G7 summit early due to the Middle East tensions, has continued to issue strong warnings to Iran.
He stated that “there are many targets left” and that “future attacks will be far greater” if Iran does not “make peace.” While the U.S. has communicated to Israel that it is “done” with its planned strikes for now, it remains prepared to respond if Iran retaliates against U.S. interests or personnel. U.S. officials have stated the recent strikes aimed to “alleviate the threat” of Iran developing nuclear weapons, not to pursue regime change.
- International Reactions: The global community remains deeply concerned. The United Nations Secretary-General Antonio Guterres expressed “grave alarm” at the U.S. intervention, calling it a “dangerous escalation” and urging de-escalation.
Russia “strongly condemned” the U.S. bombings, calling them “irresponsible” and a “gross violation of international law.”
China echoed these sentiments, condemning the U.S. strikes and urging all parties, “especially Israel, to cease fire as soon as possible.” Conversely, the UK and Australia signaled support for the U.S. actions, viewing them as necessary to prevent Iran from obtaining a nuclear weapon, while also calling for de-escalation and diplomacy. Iranian Foreign Affairs Minister Abbas Araghchi is scheduled to meet with Russian President Vladimir Putin today in Moscow, indicating ongoing diplomatic efforts.
- Humanitarian Toll: The Washington-based Human Rights Activists group has reported that Israeli strikes on Iran have killed at least 950 people and wounded 3,450 others since June 13, including 380 civilians. In Israel, at least 24 people have been killed and over 1,000 wounded.
The internet in Iran continues to face widespread disruptions, making independent verification of casualty figures challenging. Iranian authorities also reported the execution of another suspected Israeli spy today, the third such execution since the conflict intensified.
The Genesis of Hostility: A Historical Perspective
The animosity between Iran and Israel is rooted in a complex history, evolving from initially cordial relations during the Cold War to open hostility following the 1979 Iranian Revolution. Prior to the revolution, Iran was the second Muslim-majority country to recognize Israel. However, with the establishment of an anti-Western Islamic Republic, diplomatic and commercial ties were severed.
Since the early 1990s, particularly after the Gulf War, the relationship has been characterized by a “cold peace” that steadily deteriorated into a proxy conflict. Key factors driving this escalation include Iran’s nuclear program, Israel’s strong opposition to it, and Iran’s extensive support for various Islamist groups such as Hezbollah, Hamas, and the Houthis, which Israel considers terrorist organizations actively working against its security. Direct military confrontations, such as in the 2006 Lebanon War, and tit-for-tat cyberattacks and sabotage operations on infrastructure, including nuclear facilities and oil tankers, have also been hallmarks of this prolonged proxy war.
The current direct war in June 2025 follows a significant escalation in 2024. This included:
- April 2024: Israel’s strike on an Iranian consulate in Damascus, killing senior Iranian officials, led to Iran’s unprecedented direct missile and drone attack on Israel.
- July 2024: The assassinations of Hamas leader Ismail Haniyeh in Tehran and Hezbollah commander Fuad Shukr in Beirut signaled coordinated targeting of regional allies.
- September 2024: Israel launched massive airstrikes in Lebanon, killing hundreds, including Hezbollah leader Hassan Nasrallah, in a widespread retaliation campaign.
- October 2024: Iran launched another significant missile barrage at Israel, followed by Israel’s open and direct strikes on Iranian missile and air-defense sites for the first time.
- June 13, 2025: Israel launched “Operation Rising Lion,” a blistering attack on the heart of Iran’s nuclear and military structure, utilizing smuggled warplanes and drones. This directly initiated the current phase of overt hostilities.
- June 22, 2025: The United States conducted strikes on key Iranian nuclear sites, including Fordow, Natanz, and Isfahan, using powerful bunker-buster bombs, significantly escalating the conflict.
Asymmetric Power: A Look at Military Capabilities
A comparison of military capabilities reveals a dynamic where Iran often possesses a numerical advantage in personnel and some ground assets, while Israel maintains a significant qualitative and technological edge, particularly in its air force and missile defense systems.
- Personnel: Iran reportedly has 610,000 active personnel with a reserve army of 350,000. Israel, in contrast, has 169,500 active personnel and a larger reserve force of 465,000.
- Air Power: Israel’s air force is considered qualitatively superior, with 345 combat-capable aircraft and 43 attack helicopters. Iran’s air force possesses 312 combat-capable aircraft and 23 for the IRGC, but many of its airframes are decades old and lack substantial modern upgrades. The U.S. intervention with advanced stealth bombers and specialized munitions further underscores this technological disparity.
- Air Defense: Israel’s Iron Dome system is a cornerstone of its air defense, adept at intercepting incoming projectiles. Iran has developed its own air defense systems, such as the Azarakhsh, but their effectiveness against a technologically advanced adversary like Israel, now bolstered by U.S. capabilities, is less clear.
- Missile Capabilities: Both nations possess significant missile arsenals. Iran has showcased its long-range ballistic missiles, including the Khorramshahr-4, which it claims to have used in the recent conflict. Israel has actively targeted Iran’s ballistic missile and drone capabilities.
- Naval Forces: Iran’s navy is larger in terms of tactical submarines and patrol craft, while Israel has fewer, but potentially more advanced, submarines.
- Nuclear Capabilities: While Iran maintains its nuclear program is for peaceful purposes, it has enriched uranium to 60% purity, a level that raises international proliferation concerns. Israel is widely believed to possess a nuclear arsenal, though it has never officially acknowledged it. The U.S. strikes on Iranian nuclear facilities aim to dismantle Iran’s enrichment capacity, a key objective for Israel.
Global Reverberations: International Reactions and Economic Impact
The escalating conflict has drawn widespread international condemnation and calls for de-escalation. Many world leaders and international bodies, including the G7, the European Union, Sri Lanka, Malaysia, Japan, and Russia, have urged restraint and a return to diplomatic solutions. There are also concerns about Russia’s limited ability to directly support Iran due to its ongoing war in Ukraine, leading to largely diplomatic overtures from Moscow.
Economically, the war presents a dire threat to global stability. The most immediate and significant concern is the potential closure of the Strait of Hormuz, a critical chokepoint through which approximately one-fifth of the world’s oil supply and a quarter of its liquefied natural gas pass daily. The mere possibility of this closure has already caused energy prices to surge, with Brent crude prices rising significantly. Analysts warn that a full closure could push oil prices to catastrophic levels, leading to widespread inflation and potentially derailing fragile global economic recoveries. Israeli attacks on Iranian oil infrastructure, including Kharg Island, have already disrupted global supply. The United States, already grappling with inflation and debt, faces severe economic repercussions from prolonged involvement in the conflict and resultant energy shocks.
The Path Forward: Uncertainties and Challenges
As the conflict enters its second week, the immediate future remains highly uncertain. Iran has vowed retaliation for the U.S. strikes on its nuclear facilities, though the nature and timing of this response are unclear, with Iranian leaders reportedly struggling with internal communication due to Israeli strikes. The U.S. has indicated it will not conduct further strikes unless Iran or its proxies retaliate against U.S. interests, while Israel seems determined to continue its air campaign.
The humanitarian cost continues to mount, with significant casualties reported on both sides. The potential for regional spillover remains high, with Iranian-backed militias like the Houthis and Kataib Hezbollah having issued threats against U.S. forces if the U.S. deepens its involvement.
Diplomatic efforts are underway, with the ongoing meeting between Iranian and Russian foreign ministers, and other European diplomats engaging in Geneva. However, the intensity of the current hostilities makes a swift diplomatic breakthrough challenging. The long-term implications for the region, including the future of Iran’s nuclear program and the broader geopolitical landscape of the Middle East, hang precariously in the balance. The international community faces the daunting task of navigating this perilous escalation, seeking to de-escalate tensions and prevent further widespread conflict.
