Strike on the Core: U.S. Hits Iran’s Nuclear Sites – What Comes Next?
Yesterday, the U.S. did what most people assumed it wouldn't: it hit hard, in a extremely complicated air attack, Iran's nuclear facilities in Fordow, Natanz, and Isfahan. This was a major, coordinated strike that went after the core of Iran’s underground nuclear infrastructure.
President Trump addressed to the nation describing the attack as “very successful” declaring that all Iranian nuclear enrichment sites were “completely and totally obliterated”. More importantly he warned Tehran not to retaliate and instead negotiate peace terms. Today, 6/22, the General Dan Caine, Chairman of the Joint Chiefs of Staff in the Pentagon, gave more details regarding the “Operation Midnight Hammer”. According to the Pentagon, the damage caused was extremely severe but it is “too early to determine full nuclear impact”. Additionally, the Defense Secretary made it clear that the strike was not about regime change but aimed only Iran’s nuclear program. Vice President J.D. Vance stated that the U.S. is “at war with Iran’s nuclear program” and not the country itself.
As the world is watching closely, the coming days will reveal whether the U.S. strike marks the end of the threat or just the start of a new extremely dangerous chapter in the Middle East.
How Bad Was the Damage?
From what we know, the strikes were surgically executed in the largest ever operational B-2 strike, combining strategic bombers, cruise missiles, advanced decoy tactics, and electronic suppression . More specifically, the U.S. used stealth bombers, B‑2 Spirit Stealth Bombers, which flew nonstop from Whiteman AFB (Missouri) with multiple mid‑air refueling, flying into Iranian airspace under heavy deception tactics. The B-2’s dropped a total of 14 GBU‑57 Massive Ordnance Penetrator (MOP) bunker‑buster bombs, 12 on Fordow, 2 on Natanz, marking the first combat use of these 30,000 lb weapons. Additionally, Tomahawk Cruise Missiles fired from Ohio‑class submarines struck Natanz and Isfahan sites contemporaneously with the B‑2 bombs.
Fordow, the most fortified site, took a hit. Satellite photos show collapsed entrances and deep impact craters. If anything was still running down there, it probably isn’t now.
Natanz and Isfahan also took damage, though Iran hasn’t admitted how much.
According to the International Atomic Energy Agency (IAEA), there have been no detections of increased off‑site radiation levels following the U.S. strikes on Iran's nuclear facilities (Natanz, Fordow, and Isfahan). This suggest either Iran moved its enriched material, or the deepest chambers survived. Either way, that’s a detail that matters more to nuclear watchdogs than to military planners.
The bottom line is that from a tactical perspective, the strike was successful. The U.S. showcased to the World its overwhelming force, pinpoint accuracy, and total control of the air. However, strategy isn't just about bombs and targets, it's about what happens next.
Iran’s Next Move
So far, Iran hasn’t fired back with missiles. But they’ve already made a statement by threatening to close the Strait of Hormuz, which is the lifeline for a fifth of the world’s oil supply. Today, 6/22 Iran’s parliament has voted in favor of closing the strategic Strait of Hormuz in direct response to the U.S. airstrikes. However, this move is pending final approval from its Supreme National Security Council and Supreme Leader Ayatollah Khamenei. This is not just symbolic because Iran puts severe pressure on the global economy in its first retaliation action against the U.S.
Here’s what Iran’s playbook might look like:
Asymmetric warfare: Iran is too weak to retaliate with full force against the U.S. military. Instead, Tehran might activate its proxies on the region to hit regional targets and stir chaos without directly inviting another U.S. bombing run.
Naval harassment: Mines, speedboats, anti-ship missiles. The Strait of Hormuz will feel tighter and may a full blockade is under porta even though it might cause the U.S. military response.
Cyberattacks: Iran’s cyber units have capabilities and might use them against U.S. infrastructure. Cyberwarfare instead of missiles.
Diplomatic escalation: Iran can hit back to an extend without using military force. In this regard, it could kick out IAEA inspectors, announce it’s enriching uranium past weapons-grade levels, or even walk away from the Nuclear Non-Proliferation Treaty altogether. Moves like that wouldn’t just shake up the region, they’d send shockwaves through the entire global nuclear order. And Tehran knows it.
At the United Nations, Iranian diplomats are already gearing up to make their case. They’ll argue the U.S. strikes were illegal, that Iran was provoked, and that its nuclear program wasn’t a threat. Even if the U.S. blocks any formal action with a Security Council veto, Iran’s real goal may be to win over public opinion and pressure Washington diplomatically. In international forums, that kind of narrative matters.
Behind the scenes, Iran could also reach out to its closest allies—especially North Korea. The two have shared technology before, and in a moment like this, Tehran might be looking for any edge it can get. Help might not come in the form of troops or weapons, but in advice, intel, or technical support that makes the next step more dangerous for everyone involved.
Why It Matters
The American attack was not a preventive strike. It was a deliberate, visible message to the Iranian regime: time is up. And unlike previous red lines, this one was enforced.
The challenge for Iran now is that it must respond, at least to some degree. But its options are limited as the country is under immense economic strain, its military is ill-equipped for a prolonged conflict, and its regional allies are watching closely. The regime needs to project strength, but do so carefully. A misstep could trigger a second, possibly more devastating, wave of U.S. strikes. Yet if Iran stays silent, it risks losing credibility both at home and abroad.
The Risk We’re In
We’re walking a tightrope. A few miscalculations and we’re looking at a regional war. Israel is watching. The Gulf States are bracing. Oil markets are rattled. And the White House expects Iran to choose wisely its next move.
In military terms, the strike was clean. In geopolitical terms? We’ve entered a new phase, one where restraint, revenge, and deterrence are all fighting for space. This isn’t over.
