An unnamed senior Israeli official has said that the country’s goal is to topple the Iranian regime by the end of US President Donald Trump’s term in office, the Kan public broadcaster reported Monday, as the two countries are reportedly readying for another armed confrontation.

The official added that Iran is working to restore its advanced missile stocks, which were largely depleted after the 12-day war between the two countries in June, and that Israel is closely monitoring the developments.

According to a security source speaking to Channel 13, if a new confrontation materializes, “Israel will respond much more aggressively” than in previous rounds of fighting, and Jerusalem is preparing for hostilities to last far longer than 12 days this time.

The reports came a day after The New York Times reported that Tehran has greatly increased its missile production, and that senior sources increasingly believe that another war between Israel and Iran is “only a matter of time.”

Iran is working around the clock to revamp its ballistic missile systems in hopes of being able to “fire 2,000 at once to overwhelm Israeli defenses, not 500 over 12 days,” Ali Vaez, the Iran project director at the International Crisis Group, told The Times.

“Israel feels the job is unfinished and sees no reason not to resume the conflict, so Iran is doubling down preparedness for the next round,” Vaez said, adding, however, that there was no suggestion that any renewed fighting was imminent.

The Times also quoted regional officials and experts as believing that Israeli and US strikes during the war in June caused less damage to Tehran’s nuclear facilities than previously thought, and that both countries are preparing for the prospect of another round of conflict.

On June 12, Israel launched a sweeping assault on Iran’s top military leaders, nuclear scientists, uranium enrichment sites, and ballistic missile program, arguing it was necessary to prevent the Islamic Republic from realizing its avowed plan to destroy the Jewish state.

Iran has consistently denied seeking to acquire nuclear weapons. However, it enriched uranium to levels that have no peaceful application, obstructed international inspectors from checking its nuclear facilities, and expanded its ballistic missile capabilities, all while regularly threatening to flatten Israeli cities. Israel said that leading up to the June war, Iran had taken steps toward weaponization.

Iran retaliated to Israel’s strikes by launching over 500 ballistic missiles and around 1,100 drones at Israel.

The attacks killed 32 people and wounded over 3,000 in Israel, according to health officials and hospitals. More than 1,000 people died in Iran.

In all, there were 36 missile impacts and one drone strike in populated areas of Israel, causing damage to 2,305 homes in 240 buildings, along with two universities and a hospital, and leaving over 13,000 Israelis displaced.
