The hubris of the United States is on clear display on a day like today, where late Saturday, we used so-called bunker buster bombs to attack the uranium enrichment capacity of Iran at three sites: Fordow, Natanz and Isfahan. The president said in an address Saturday night, “Iran’s key nuclear enrichment facilities have been completely and totally obliterated.” I’m calling bullshit. So are a lot of folks who know more than I do.
“It is impossible to know at this stage whether this operation accomplished its objectives,” ranking member of the House Intelligence Committee Jim Himes (D-Conn.), said in a statement.
Gen. Dan Caine, chairman of the Joint Chiefs of Staff, said in a news conference Sunday that the Fordow, Natanz and Isfahan nuclear facilities “sustained extremely severe damage” but it was too early to tell the scale of destruction, according to the Washington Post.

Dr. Ira Helfand addressed the question at the heart of this:
What if the United States attacks Fordow with a GBU-57 “bunker buster” bomb and the bomb does not take out the deeply buried site? Does the United States escalate up to the use of a nuclear weapon?
A 2005 report issued by Physicians for Social Responsibility examined the effects of an attack on the Iranian nuclear facility in Isfahan with a 1.2-megaton B-83 thermonuclear warhead, then under consideration for use in a Robust Earth Nuclear Penetrator (the “bunker buster”). The study used software known as the Hazard Prediction and Assessment Capability—developed by the Defense Threat Reduction Agency—to model nuclear weapons explosions’ effects. The study found that the attack could kill 3 million people—half of them from radiation sickness—and that the radioactive fallout would spread over a wide area of Iran, Afghanistan, and Pakistan.
The population near Fordow is much smaller than in Isfahan, but the death toll and radioactive contamination resulting from the use of a nuclear weapon there would still be catastrophic. (“Why Congress and the people should stop Trump from attacking Iran,” by Dr. Ira Helfand, Bulletin of the Atomic Scientists, June 19, 2025).
The American hubris to which I referred is our decades long failure to comply with Article VI of the Treaty on the Non-proliferation of Nuclear Weapons. Both we and Iran are parties to the treaty. The idea the U.S. could escalate this situation to include use of nuclear weapons would not be an option if we were in compliance with the treaty.
The irony of Saturday’s bombing is it may cause Iran to withdraw from the treaty and develop a nuclear program which includes nuclear weapons. This is something that according to people who read the intelligence before the bomb-dropping, was not previously on the table.
As Daryl Kimball of the Arms Control Association put it, “The U.S. military strikes on Iranian nuclear targets, including the deeply fortified, underground Fordow uranium enrichment complex, may temporarily set back Iran’s nuclear program, but in the long term, military action is likely to push Iran to determine nuclear weapons are necessary for deterrence and that Washington is not interested in diplomacy.”
My initial reaction to news of the bombing persists: “The bombing of Iran’s fuel enrichment sites was an illegal, useless act that makes the world less safe.”
