TEL AVIV—Prime Minister Benjamin Netanyahu said on Sunday that Israel was "very, very close" to achieving its war goals following U.S. airstrikes on Iran’s nuclear facilities the previous night. But, he emphasized, "We are not done."

In a press conference, Netanyahu hailed the American operation as a pivotal moment in the 10-day military campaign against Iran, saying it had significantly accelerated Israel’s push to dismantle Iran’s nuclear and ballistic missile programs. He singled out the U.S. strike on the Fordow enrichment site, calling the damage "tremendous."

"We are progressing toward the goal of removing both threats together," Netanyahu said. "We will not end this action—this historic operation—before we achieve all our objectives."

On Sunday, the Israeli military conducted at least two major waves of airstrikes across Iran that struck dozens of missile, drone, and air defense sites. Among the targets was a surface-to-air missile launcher in central Tehran. The Israeli military said the strikes also hit radar and satellite systems in western Iran, as well as missile storage and launch infrastructure in Kermanshah and Bahman. Semi-official Iranian news agencies reported that three members of the Islamic Revolutionary Guard Corps were killed in a strike in the western Zanjan province, and explosions were heard in the southern port city of Bushehr, home to Iran’s only nuclear power plant.

Several current and former Israeli officials told the Washington Free Beacon that the joint campaign has already dealt a severe blow to Iran’s nuclear program. But they said Israel must continue striking to dismantle Iran’s remaining missile capabilities—a mission they estimated would take another one to three weeks.

"We need more time to destroy the infrastructure," said Yaakov Amidror, a former national security adviser to Netanyahu. "The best way to dismantle it is what we are doing with our air force."

"We’re making progress," he said. "Clearly, the fewer launchers there are, the less they can launch missiles at us."

In a confidential briefing to the Knesset Foreign Affairs and Defense Committee on Sunday, lawmakers were told that Iran had about 2,500 ballistic missiles and 500 launchers on June 13, when Israel launched the campaign with a surprise attack, two participants confirmed to the Free Beacon. Iran has launched more than 450 missiles at Israel, and Israel has destroyed hundreds more along with some 200 launchers.

"The question is if 60 percent [of the launchers destroyed] is enough for us, or if we want 70 percent or 80 percent or 90 percent," said Ohad Tal, a member of the Foreign Affairs and Defense Committee from the Religious Zionism party. "I think the answer is that we would want to do as much as possible."

The Israeli military has also destroyed three of eight Iranian anti-aircraft systems, officials said, and is continuing to target military radar and satellite assets to establish full air superiority over Iranian territory.

Amir Avivi, a former senior Israeli military officer who has advised the Netanyahu government through its more than 20-month war with Iran and its network of terrorist affiliates, said Israel’s ambitions had grown over the course of the successful campaign against Iran.

"The more we do, the more appetite we have," he said. "We are succeeding. We can do much more. Then, we want to extend the time."

A senior Israeli official, speaking on condition of anonymity, said, "A lot has been accomplished. More than expected. Operation Rising Lion will continue until the objectives are reached."

Netanyahu said the campaign was being carried out in full coordination with President Donald Trump, who authorized the U.S. strikes.

"I work in extremely close coordination with President Trump," he said. "There has never been coordination like this between an American president and an Israeli prime minister."

Israeli and American intelligence services were cooperating "down to the smallest details," he added.

Another unresolved issue was Iran’s stockpile of yellowcake uranium. Amidror said Israel believes Iran still holds 400 kilograms of yellowcake. Tal said the uranium in question was not enriched to weapons-grade and is not seen as a red line.

"They don’t have the facilities, and they don’t have the knowledge, and they don’t have the scientists," he said. "They can’t really do anything with it."

The current and former officials agreed that Iran is unlikely to agree to fully dismantle its nuclear program, as Israel and the United States have demanded.

"I don’t think they’re going to accept the deal," said Yossi Kuperwasser, a former senior Israeli intelligence officer who served as director general of Israel's Strategic Affairs Ministry. "It’s not Iranian."

Netanyahu reiterated in his press conference that a deal would only be acceptable if it results in total dismantlement.

"A good deal dismantles all the nuclear infrastructure—blows it up—and all of their ballistic missile production capabilities," he said. "That would be good. But the Iranians were not willing to agree to that. And now it is happening—because they refused."

Despite escalating threats from Iran, Netanyahu said Israel would not be dragged into a war of attrition.

"We are not done," he said. "But we also will not end this action—this historic operation—before we achieve all our objectives."

Senior Israeli officials described three possible scenarios for how the war could end. The first is regime change in Iran—an outcome they said would be desirable but is not Israel’s official objective.

"We cannot make any regime change," said Amidror. "We can make the regime weaker."

"We are not asking for the regime to fall," said Kuperwasser. "But we are creating the conditions that might be conducive to it. Weaken the regime, and let the people decide."

The second scenario is a negotiated settlement. The officials said any acceptable deal would require Iran to dismantle its nuclear and missile infrastructure and accept intrusive international monitoring.

"If they accept the deal tomorrow," Kuperwasser said, "then I guess we should stop attacking."

But officials said Iran is unlikely to agree to such terms—especially now. Since the U.S. strikes, Iran’s foreign minister Abbas Araghchi has declared that "diplomacy is not an option," and accused Washington of "blowing up all diplomatic efforts." The regime said it would pursue "everlasting consequences," and a senior adviser to Supreme Leader Ali Khamenei said the military bases involved in the U.S. attack were now "legitimate targets."

The third scenario—and the one several officials called the most realistic—is that Israel continues degrading Iran’s military capabilities until the immediate threat is neutralized and then enforces a standing policy of deterrence.

"The new Israeli security doctrine says we should not allow threats to develop anywhere that are intended to destroy the state of Israel," Kuperwasser said. "That’s what we do in Gaza and Lebanon, and that’s what we are now doing in Iran."

Netanyahu has not committed publicly to a specific endgame.

"I can imagine several options," he said Sunday. "But I don’t think it helps us achieve the full goals of the war to lay them out here."
