Waltz’s comments came hours after Iranian foreign ministry spokesman Esmaeil Baqaei went further in the other direction, calling the continued U.S. naval blockade of Iran’s ports “unlawful and criminal” and a “war crime and crime against humanity.” Baqaei said it was the blockade, not Iran’s actions in the Strait of Hormuz, that was violating the Pakistan-brokered ceasefire.

The pushback isn’t only coming from Iran. Conservative commentator Tucker Carlson made headlines earlier this month when he called the idea of striking Iran’s civilian infrastructure “vile on every level.” “It begins with a promise to use the U.S. military, our military, to destroy civilian infrastructure in another country, which is to say, to commit a war crime, a moral crime against the people of the country,” Carlson said in a video on April 7.

Under Additional Protocol I to the Geneva Conventions, “civilian objects shall not be the object of attack,” and strikes are prohibited if they “may be expected to cause incidental loss of civilian life, injury to civilians, damage to civilian objects, or a combination thereof, which would be excessive in relation to the concrete and direct military advantage anticipated.”

Trump threatened on Truth Social earlier Sunday to “knock out every single Power Plant, and every single Bridge, in Iran” if a deal isn’t reached. The two-week ceasefire expires Wednesday.
