Prime Minister Netanyahu is reportedly set to use a meeting with US President Trump later this month to present plans for a renewed attack on Iran.
Israel launched Operation Rising Lion in June, inflicting significant damage on Iranian nuclear facilities, opening a 12-day war with the Islamic Republic, which responded with missile strikes against major civilian population centres.
The US would later intervene in the conflict, using B-2 stealth bombers and "bunker-busting" munitions to severely damage the underground nuclear site at Fordow.
However, reports surfaced soon after the war that the strikes may have failed to destroy Iran's stock of enriched uranium, which could be used to make nuclear weapons.
Sources reportedly told NBC News that Israel has again become alarmed by the rate of Tehran's ballistic missile production, which one estimated could reach 3,000 per year if left unchecked.
The report suggests that Netanyahu will present Trump with potential responses when he visits the president's Mar-a-Lago resort at the end of the month.
"The nuclear weapons program is very concerning. There’s an attempt to reconstitute. [But] it’s not that immediate,” said one source.
"The threat of the missiles is very real, and we weren’t able to prevent them all last time,” added another.
Less than 24 hours after the report emerged, IDF Chief of Staff Lieutenant General Eyal Zamir further fed speculation of fresh moves against Iran during a speech at army headquarters in Tel Aviv.
He pledged that the IDF would hit Israel's enemies "wherever required, on near and distant fronts alike".
He went on to name the Islamic Republic, saying: "At the centre of the longest and most complex war in Israel’s history stands the campaign against Iran.
"Iran is the one that financed and armed the ring of strangulation around Israel and stood behind the plans for its destruction."
Both Israel and Iran declined to comment on NBC's report, but a White House spokesperson was firm: "As President Trump has said, if Iran pursued a nuclear weapon, that site would be attacked and would be wiped out before they even got close."
