Israeli Prime Minister Naftali Bennett and Defense Minister Benny Gantz made a surprise visit to troops carrying out war exercises in northern Israel, which included a landing operation in a mountainous area similar to the topography of Iranian mountains.
Some 3,000 soldiers from the Golani Brigade, armored units, artillery, and reservist brigades participated in the drill.
"No matter what happens between Iran and the world powers — and we are certainly concerned about the fact that there is insufficient severity in dealing with Iranian violations — Israel will protect itself with its forces," Bennett said ahead of the resumption of the nuclear talks in Vienna.
“The world needs to act against Iran, and Israel is prepared to do what is needed on all of these fronts and the northern front in particular,” Gantz said after visiting the forces.
Later, Bennett's office issued a statement saying the Prime Minister assessed the situation with Chief of Staff Lieutenant-General Aviv Kochavi.
US Special Envoy for Iran Robert Malley met with Israeli officials, including alternate Prime Minister and Foreign Minister Yair Lapid.
Malley aims to coordinate with Mideast allies before Washington resumes the indirect talks with Tehran to revive the nuclear deal in Vienna.
Sources close to Lapid said the FM told Malley that Iran has no intention of returning to the deal.
Lapid believes Tehran is simply trying to buy time through negotiations over its nuclear program until the issue of rejoining the 2015 nuclear deal is no longer relevant.
The sources confirmed that Lapid raised Israel's technical intelligence concerns about returning to the agreement and lifting sanctions.
An official from Bennett's office said Israeli officials fear that the different positions between the former and the current US administration will increase Iran's intransigence and perhaps manipulation until Tehran becomes a "nuclear threshold state."
Israeli leaders discussed with Malley the military option as a serious and essential alternative.
The former head of Israeli military intelligence research, Brigadier General Yossi Kuperwasser, said the US is sending messages that it is not interested in war and Israel is not behaving as if it wants war with Iran. He indicated Tehran might increase its provocations.
Kuperwasser believed Iran is a few weeks away from producing military-enriched uranium for the first explosive device and has started producing metallic uranium, which can be interpreted as having intentions to produce nuclear weapons.
Israel is not ready to act against Iran because it does not have US support or the operational capabilities, the official believes.
