New York Times: “Over the past year, U.S. airstrikes have crippled Iran’s nuclear program. Several Iranian nuclear facilities lie in ruins. And Iran’s stockpile of highly enriched uranium — “nuclear dust,” as President Trump calls it — is thought to be deeply buried under rubble.”

“But even after a U.S. bombing raid last June and more than five weeks of attacks on Iran since February, one suspected nuclear site remains untouched. Experts say the underground facility, known as Pickaxe Mountain, is buried so deep that it may lie beyond the reach of America’s most powerful bunker-buster bombs.”

Richard Haass: “The principal reality now is that neither the United States nor Iran would benefit from a resumption of fighting. We have all but run out of targets, and the Trump administration should have learned by now that bombing will not lead Iran to capitulate. Nor will it produce regime change.”

“As for Iran, it has already shown it is both willing and able to disrupt shipping and threaten the energy infrastructure of its neighbors. But carrying out such a threat at this stage would lead to the destruction of its own energy infrastructure, making economic recovery all but impossible.”

“The Iran war is risking America’s global security ties and damaging its reputation, especially among the world’s Muslims, according to a set of State Department cables,” Politico reports.

“The cables, dated Wednesday, described the fallout of the war for America’s standing in three countries in different parts of the world: Bahrain, Azerbaijan and Indonesia.”

Sen. Susan Collins (R-ME) said Thursday that she believes the U.S. war in Iran will need congressional authorization once it hits a 60-day mark that past legislation established for military conflicts — and she doesn’t think she’d vote for it, Semafor reports.

Said Collins: “It is very likely that I would vote not to authorize further hostilities.”
