Trump Plays the Ground Troops Card: 5 Urgent Scenarios the '4–5 Week War' Warning Poses for Korea's Energy, Exports, and Overseas Nationals
President Trump declared the Iran war could last 4–5 weeks or longer, and publicly refused to rule out deploying ground troops. As the front widens — with a prolonged Hormuz blockade, Kuwait's accidental shoot-down, and escalation into Lebanon — 21,000 Koreans in the Middle East and Korea's 70% oil dependency are making Korea one of the front-line casualty nations.

Why you need to watch this now: The moment Trump said he "doesn't rule out" ground troops, the Iran war crossed a threshold — escalating from a short-duration air campaign into a potential large-scale ground war across the Middle East.
TL;DR
- President Trump publicly stated that the Iran war will last 4–5 weeks and could go longer
- He explicitly refused to rule out deploying ground troops — the single biggest wildcard in the conflict
- The Iranian front is spreading to Lebanon and Kuwait, with an accidental shoot-down raising the risk of uncontrolled escalation
- 21,000 Koreans are in the Middle East; Korea depends on the Hormuz Strait for 70% of its oil
- The KRW/USD rate has broken 1,500 won, and the KOSPI fell a record –7.24% in a single session
1. The Facts: What Trump Actually Said
On March 3–4, 2026 (US local time), President Trump declared that "the Iran military operation will take 4–5 weeks — and could take longer." He went a step further by stating that he "doesn't rule out" deploying US ground troops, bringing fears of a wider front to their highest point yet.
The US–Israel military campaign against Iran, which began under the operation name 'Operation Epic Fury', entered its fifth day with the following escalations:
- Lebanon: Renewed clashes with Hezbollah, an Iranian-backed force
- Kuwait: Kuwait's air defenses accidentally shot down a US F-15E fighter jet (all 6 crew members survived)
- Strait of Hormuz: Iran continues to threaten to "burn oil tankers"; the US CENTCOM announced that 11 Iranian naval vessels have been sunk
2. Why the Ground Troops Statement Is a Game-Changer
Air strikes and naval blockades can eventually be converted into negotiating leverage — but ground troop deployment means a fundamentally different level of physical intervention.
- Entry into Iranian territory means direct ground combat with the IRGC (Islamic Revolutionary Guard Corps) — rapid increase in personnel and equipment losses
- Shia militia fronts in Iraq, Syria, and Yemen could simultaneously open, spreading the conflict further
- Russia and China's diplomatic pushback will intensify, raising the risk of linkage with anti-Russia and anti-China sanctions
- Indefinite extension of the war — the "4–5 weeks" statement itself already implies a longer conflict than originally projected
3. Context: Why Korea Is on the Front Lines
| Indicator | Current Status |
|---|---|
| Oil dependency on the Middle East | ~70% (most routed through the Strait of Hormuz) |
| Korean nationals in the Middle East | ~21,000 or more |
| KRW/USD exchange rate | Broke 1,500 won (intraday on 3/4 — first time since 2009, 17 years) |
| KOSPI single-day drop | –7.24% — largest single-day decline on record (3/3 close) |
| Airline stocks | Korean Air –10.32%, Hanjin KAL –10.11% |
If the war extends beyond 4–5 weeks, a Hormuz blockade could become a reality — leading to an oil price scenario of $120–$150/barrel (forecast by JP Morgan and SEB). The Hyundai Research Institute has warned that at $150 oil, Korea faces +2.9%p inflation and a –0.8%p growth shock.
