President Joe Biden said Thursday that the United States is “not going to wait forever” for Iran to rejoin a dormant nuclear deal, a day after saying he’d be willing to use force as a last resort against Tehran if necessary.

Biden made the comments at a news conference after meeting with Israeli Prime Minister Yair Lapid following one-on-one talks in which they discussed Iran’s rapidly progressing nuclear program.

“We’ve laid out for the leadership of Iran what we’re willing to accept in order to get back into the JCPOA. We’re waiting for their response. When that will come, I’m not certain.,” Biden said, using an acronym for the Iran nuclear deal. “But we’re not going to wait forever.”

Resurrecting the nuclear deal brokered by Barack Obama’s administration and abandoned by Donald Trump in 2018 was a key priority for Biden as he entered office. But administration officials have become increasingly pessimistic about the chances of Iran returning to compliance.

Biden and Lapid on Thursday discussed Iran’s rapidly progressing nuclear program, with the Israeli leader vowing afterward that “there will be no nuclear Iran.”

The U.S. president, who is set to travel to Saudi Arabia on Friday, said he also stressed to Lapid the importance of Israel becoming “totally integrated” in the region.

Their one-on-one talks are the centerpiece of a 48-hour visit by Biden aimed at strengthening already tight relations between the U.S and Israel. The leaders also issued a joint declaration emphasizing military cooperation and a commitment to preventing Iran, which Israel considers an enemy, from obtaining a nuclear weapon.

“We discussed the Iranian threat,” Lapid told reporters afterward. “There will be no nuclear Iran.”

Israeli officials have sought to use Biden’s first visit to the Middle East as president to underscore that Iran’s nuclear program has progressed too far and encourage the Biden administration to scuttle efforts to revive a 2015 agreement with Iran to limit its development.

In the joint statement, the United States said it is ready to use “all elements of its national power” to prevent Iran from obtaining a nuclear bomb.

Biden, in an interview with Israel’s Channel 12 that aired Wednesday, offered strong assurances of his determination to stop Iran from becoming a nuclear power, saying he’d be willing to use force as a “last resort” if necessary.

Iran announced last week that it has enriched uranium to 60% purity, a technical step away from weapons-grade quality.

The joint declaration being announced Thursday could hold important symbolic importance for Biden’s meeting this weekend with Arab leaders in Saudi Arabia as he seeks to strengthen a regionwide alliance against Iran.

“I talked about how important it was … for Israel to be totally integrated in the region,” Biden said after the one-on-one meeting with Lapid.
