BEIRUT (AP) — President Donald Trump acknowledged criticizing Israeli Prime Minister Benjamin Netanyahu as “crazy” in a phone call that involved expletives, saying he was “a little bit perturbed” that Israel’s fighting with Hezbollah militants in Lebanon was holding back peace talks with Iran.

But even as the U.S. president conceded the tensions in an interview released Wednesday, he insisted that his relationship with Netanyahu was solid and that they connected, in part, because they are both “wartime” leaders.

“We’ve worked very well together. I like Bibi a lot. And I work very well with him,” Trump told The New York Post’s “Pod Force One.”

In an interview on the American business-news channel CNBC, Netanyahu responded that he and Trump sometimes have “tactical disagreements” but have “common goals” and “agree on the main things.”

“He respects me. I respect him. We always find a way to work out our differences,” the prime minister said.

The president’s comments about the Monday call offered a sign of the growing pressure he faces to resolve the Iran war as higher energy prices and economic uncertainty threaten Republican prospects in the midterm elections and hamper global commerce.

Talks have dragged on for weeks as mediators seek to extend a fragile ceasefire into a more enduring truce. The negotiations are further strained by Israel’s broadening war with the Iranian-backed militia group in Lebanon. The conflicts have become increasingly intertwined as Iran insists that any potential truce in the war there must also quell the fighting in Lebanon.

Trump remained noncommittal about a timeline for settling the Iran conflict, saying the Strait of Hormuz might stay blocked through the Labor Day holiday on Sept. 7. He has insisted that Iran stop any efforts that could lead to a nuclear weapon and that the strait be reopened for shipments of oil and natural gas.

“I don’t know. I mean, I think it could be (closed through Labor Day), but I think it’s unlikely. I think that we’ll have it. I think this will resolve itself fairly quickly,” Trump said.

Iran’s Supreme Leader Mojtaba Khamenei, who succeeded his late father, is “involved” in peace talks, Trump added.

“They have a lot of respect for him,” the president said in the interview.

Trump said that Khamenei is not doing well due to wounds sustained in an airstrike, but “they say he’s giving approval because that’s the way it has been for a long, long time.” Khamenei’s father was killed in an airstrike when the U.S. and Israel attacked Iran at the end of February.

Meanwhile in the Persian Gulf region, Kuwait briefly shut its main airport Wednesday after Iranian drones hit a passenger terminal building, killing one person and wounding dozens. It was the latest in the back-and-forth attacks by Tehran and Washington that have tested the ceasefire.

The strike again brought home the risks to residents and travelers in Gulf countries that had considered themselves relative safe havens before the war, now in its fourth month.

The path toward a lasting ceasefire between Israel and Hezbollah remained unclear as hostilities continued in Lebanon.

An Israeli strike Wednesday hit a car on a busy highway just south of Beirut, hours before the second day of talks between Lebanon and Israel in Washington were set to take place. The strike in Khaldeh came without warning, and it was not immediately clear if the person targeted was killed.

Israel and Lebanon on Monday reached a U.S.-brokered agreement in which Israel would not strike Beirut’s southern suburbs and Hezbollah would end its attacks on northern Israel.

The agreement was made hours after Israel announced that it was going to launch strikes across the sprawling urban neighborhoods near the Lebanese capital in what would have been the most intense strikes since a nominal ceasefire went into effect on April 17.

Lebanon hopes to widen the scope of the ceasefire so it becomes comprehensive across the country. Israel wants to disarm Hezbollah immediately before the Israeli military ends its operations in Lebanon and withdraws its troops from dozens of villages and towns.
