Iran and the United States are no longer in a “direct conflict of interests” as of March 1, 2026—in fact, they are already at war. On February 28, the US and Israel launched a large-scale joint strike against Iran (code-named “Epic Fury”), directly killing Iran’s top leader, Khamenei. Targets included residual nuclear facilities, missile production sites, naval forces, and key government buildings. President Trump publicly called on the Iranian people to “take over the government,” essentially pushing for regime change.

1. Has Iran threatened the US homeland militarily?
No.
Iran has not yet developed intercontinental ballistic missiles (ICBMs) capable of reaching the US mainland. US intelligence estimates that even with full development, it would take about 10 years. Iran’s missile threat primarily covers Middle Eastern US military bases, Israel, Saudi Arabia, and regional forces—not the US itself. US officials and think tanks repeatedly confirm that Iran’s direct physical threat to the US homeland is very low, with more potential for “targeted assassinations, terrorist attacks, and cyberattacks,” rather than missile strikes on US soil.

2. Has Iran challenged US dominance economically or technologically?
Not at all.
Iran’s GDP is roughly $400-500 billion (worse off after sanctions and war), definitely smaller than some developed Chinese provinces. Technologically, aside from regional advantages in missiles and drones, the overall gap with the US is generational. Iran simply does not have the capacity to challenge US global economic or technological hegemony.

3. Why does the US bother to intervene so far away? Is it economically worthwhile?
The mainstream US strategic logic has never been “how much is Iran worth,” but rather that three issues combine to form a “strategic tumor” that must be eliminated:
- Nuclear program (despite being bombed twice, there are still hundreds of kilograms of highly enriched uranium possibly hidden underground, capable of “breaking out” to weapons-grade at any time)
- Proxy networks (Hezbollah, Houthi, Iraqi Shia militias, remnants of Hamas, etc.), which continue attacking US forces, oil tankers, and Israel, maintaining instability in the Middle East
- The Strait of Hormuz and oil pricing power (as long as Iran threatens to blockade or attack oil tankers, global oil prices can skyrocket; although the US produces a lot of oil, its allies and the global economy remain highly sensitive)

The economic costs are actually very high:
- Oil prices could surge to $90-130 per barrel (or higher), with US gasoline prices easily exceeding $4-5 per gallon
- US military bases, fleets, and personnel in the Middle East face saturation attacks from missiles and drones
- Long-term occupation, stabilization, and humanitarian costs (similar to Iraq 2.0)
- Disruption of global supply chains, with China and Russia seizing the opportunity to expand influence

However, the Trump administration’s calculation is “short-term pain for long-term gain”: destroy Iran’s nuclear and missile capabilities, decapitate its leadership, incite internal uprisings and regime collapse—solving the Middle East’s biggest headache once and for all, while also giving Israel a free hand and providing security guarantees to Sunni countries like Saudi Arabia.

4. Are there irreconcilable life-and-death conflicts?
From Iran’s perspective: yes, and it’s a matter of survival—America and Israel want Iran to abandon nuclear deterrence, regional influence, and even the current regime itself.
From the US perspective: Iran may not be an “existential enemy,” but as long as it insists on “nuclear thresholds, proxy wars, and anti-American ideology,” it will always be a “chronic cancer” in the Middle East, capable of mutating into a nuclear-armed anti-American axis (Iran + North Korea + Russia + China loosely linked).

In summary:
Iran is too weak to directly threaten the US homeland and core interests, but through nuclear brinkmanship, proxy bloodletting, and control of global energy chokepoints, it makes the US feel that “keeping it around costs more and is riskier.”
It’s no longer a question of “whether to intervene,” but rather “it’s already happening, and it doesn’t look like it will stop anytime soon.”
