From Hormuz deployment talks to party reactions and global positions, all in one place
📌 Post Summary
The US and Iran signed a ceasefire in April, but on September 1 the US struck Iranian Revolutionary Guard-linked facilities again, reigniting the war. Iran immediately retaliated with missile and drone strikes against countries in the region. Amid this, the South Korean government is reviewing sending maritime patrol aircraft and a support vessel to the Strait of Hormuz, with reports suggesting a troop deployment motion could soon go to the National Assembly. The ruling party is divided between caution and outright opposition, while progressive allied parties are firmly against it. The UK, France, and Germany have already deployed naval assets, while China and Russia showed solidarity at the SCO summit while stopping short of military involvement. The UN Security Council held an emergency session urging restraint.
The war triggered by the US-Israeli strikes on Iran in late February eventually reached a spring ceasefire after a rocky path, but September has brought a return to full-scale armed conflict. This renewed clash has grown beyond a US-Iran bilateral issue into a matter entangling allied nations’ military contribution demands — including Korea’s — with the international community’s complex interests. Here’s the background, Korea’s deployment review, and reactions at home and abroad.

1. Timeline — From Ceasefire to Renewed Strikes
On February 28, 2026, the US and Israel carried out large-scale preemptive strikes targeting Iran’s leadership, including Supreme Leader Khamenei, and key facilities, citing the goals of halting Iran’s nuclear program and regime change. Iran responded by blockading the Strait of Hormuz and striking US bases in the region, spreading the conflict across multiple fronts; global oil prices briefly approached $100 a barrel. An April memorandum of understanding signed in Islamabad brought a ceasefire, though sporadic clashes continued, and tensions flared again in July over a controversy involving an Iranian delegation’s aircraft.
Then on September 1 (local time), US forces struck Iranian Revolutionary Guard Corps (IRGC)-linked air defense, radar, and maritime facilities again. US Central Command (CENTCOM) said the strikes were a response to recent IRGC attempts to attack commercial vessels and US forces in the Strait of Hormuz. Iran immediately claimed it had “begun retribution the aggressors will regret,” saying it shot down a US MQ-9 drone, and launched missile and drone attacks on regional countries including Bahrain and Kuwait, raising fears of further escalation.
2. Korea’s Deployment Review — What, and Why
The Korean government is reviewing a ‘military contribution’ to international efforts to secure freedom of navigation in the Strait of Hormuz. A senior presidential office official said on September 4 that “a substantive contribution includes a military contribution,” noting that a range of options, both combat and non-combat, are on the table. Assets under discussion include P-8A maritime patrol aircraft, a naval support vessel, and an explosive ordnance disposal (EOD) team. The Ministry of National Defense has said it has “actively participated from an early stage in international discussions to restore freedom of navigation in the Strait of Hormuz.”
Under Korea’s constitution, sending troops abroad requires National Assembly approval, and a deployment motion needs a majority of members present and a majority of those present voting in favor to pass. Government officials have downplayed a direct link to President Trump’s comments, but the backdrop includes Trump pressing Korea, China, Japan, France, and the UK since March for military contributions to Hormuz, and a recent Fox News interview in which he said “Korea did not help with the Iran situation.” Some analysts also see a possible connection to the recent US pressure over targeted chip tariffs, with deployment potentially serving as a card to help repair the Korea-US relationship.
3. Domestic Political Reaction — Caution Across the Board, Opposition From Progressive Allies
The ruling Democratic Party has not issued a formal position and is maintaining a cautious stance. Chief spokesperson Park Sung-joon said the issue “should wait until the National Defense Committee’s views are fully gathered.” This caution is widely attributed to the trauma of the Roh Moo-hyun-era Iraq deployment vote, when the then-ruling party itself split, 49 in favor to 43 against. Views differ within the party too — Rep. Lee Ki-heon of the Foreign Affairs and Unification Committee said “even a non-combat deployment is, in essence, clear participation in a war” and stated he would not consent to it, while others argue for a cautious approach grounded in national interest.
Progressive allied parties have taken a harder line. Rebuilding Korea Party floor leader Kim Joon-hyung noted that “even the Yoon Suk-yeol government didn’t openly send troops to the Ukraine war,” while Progressive Party lawmaker Jung Hye-kyung said “what President Lee Jae-myung should be doing right now is not joining the war in Hormuz, but stopping the war.” The main opposition People Power Party has taken a wait-and-see approach, saying it wants to see the US’s formal request and the government’s response first — though there is no disagreement across party lines that any deployment would require a National Assembly floor vote and bipartisan consultation.
4. International Reaction — Deployed, Watching, and Critical
The UK, France, and Germany have already sent naval assets, including warships, to the Strait of Hormuz to help secure freedom of navigation. The European Union issued a statement on August 31, tied to the G20 finance ministers’ meeting, saying it “welcomes efforts to ensure Iran ceases its destabilizing activities and engages in good-faith peace negotiations, including through additional economic pressure” — a reference to the US-led economic sanctions campaign. Iran’s Foreign Ministry spokesperson sharply criticized the EU’s position in response.
China and Russia, by contrast, have condemned US unilateralism while drawing a clear line against direct military involvement. At the Shanghai Cooperation Organisation (SCO) summit held in Kyrgyzstan through September 1, Chinese President Xi Jinping, Russian President Vladimir Putin, Iranian President Masoud Pezeshkian, Indian Prime Minister Narendra Modi, and leaders from 17 countries — along with UN Secretary-General António Guterres — gathered to project unity. Pezeshkian reportedly conveyed there that he wants to resolve the dispute with the US through negotiation. Japan, which had earlier expressed willingness to join a European four-nation joint statement on Hormuz navigation safety, has kept a cautious stance on whether to send its Self-Defense Forces, saying “nothing has been decided,” and — like Korea — has been putting off a final decision. The UN Security Council held an emergency session at the request of Bahrain, France, Russia, and China, among others, with Secretary-General Guterres urging a return to negotiations, warning that “failure to prevent further escalation will result in a larger conflict with enormous consequences for civilians and regional stability.”

5. What to Watch Next
In the near term, the key variable is whether Korea’s government actually submits a deployment motion to the National Assembly, and if so, at what scale and with what mission. The presidential office has said it “can act within a range that doesn’t seriously undermine readiness on the Korean peninsula,” suggesting a limited role — such as maritime patrol or mine clearance — is more likely than a large combat deployment. President Lee Jae-myung may also discuss the Hormuz issue at a summit with French President Emmanuel Macron on September 8.
Internationally, the key questions are whether the US continues to escalate, how far Iran’s further retaliation extends, and whether China and Russia move beyond diplomatic backing via the SCO toward more substantive involvement. Experts note there is “no cheap, easy, or clean military option” when it comes to Iran, suggesting the burden of a prolonged conflict weighs on the US domestically as well.
📌 Good to Know
- Whether and how Korea will deploy troops has not been finalized. National Assembly approval is still required, so any actual deployment could take time.
- This is an issue that divides opinion within the ruling party itself, not just between parties. It’s worth following how the National Assembly debate unfolds rather than drawing conclusions from any single party’s stance.
- The Strait of Hormuz carries a significant share of Korea’s oil imports, so shifts in the situation could increase volatility in global oil prices and shipping costs.
- Depending on whether the conflict escalates or a ceasefire is reached, financial market volatility — in stocks, currencies, and related assets — could widen too, so it’s worth following the news closely.
This renewed conflict is unfolding within a larger framework that goes beyond the US-Iran bilateral dispute — one involving burden-sharing among allies and a broader realignment of international power. Because Korea’s deployment decision remains fluid, contingent on both National Assembly debate and how the situation on the ground develops, it’s worth continuing to follow the decision-making process closely.
