Yisrael Beytenu Leader MK Avigdor Liberman warned that the agreement between the US and Iran will cause Tehran to become a nuclear power in a Tuesday interview with 103FM.
"This agreement definitely turns Iran into a nuclear power," Liberman said.
However, he did not directly complain about the Trump administration's goal of seeking a deal, saying they are simply acting in their own interests.
"We have different interests. The US president is interested first and foremost in fuel prices. For us, this is a matter of existing or ceasing to exist, and therefore we need to act accordingly," he said.
"We need to live with this. I have no complaints against the Americans. There are people here who expect the US to act according to Israeli interests, but no. I thank the US for what they have done," he added.
Instead, he laid blame on Israeli officials. "For three years, this entire impotent government dealt only with talk and declarations, with their political agenda. For three years, there has been no decisive outcome. They should only complain about themselves," Liberman stated.
Israel, however, should stand for its own interests even when it may cause confrontation with the US, he continued.
"Of course, they can tell Trump 'no,'" he said.
He also noted how Prime Minister Benjamin Netanyahu's trial causes harm to his judgment and credibility.
"I have never seen a press conference where a prime minister speaks for many minutes and does not say a single word of truth - a frightened, alarmed man who tried to save himself. He lied to the entire people of Israel," Liberman said.
Netanyahu used to know "how to say 'no' and stand up to [former president Barack] Obama, and also to [former secretary of state Hillary] Clinton," and "not to subordinate the entire Israeli people to a private agenda," he added.
Liberman served as the director-general of the Prime Minister's Office during the period when Clinton was secretary of state.
The current situation is "simply complete submission" by Netanyahu, he said. "All that interests Netanyahu is canceling his trial and international arrest warrant - nothing else."
"The tone and language [US President Donald] Trump uses against Israel is unprecedented. Netanyahu has turned us into a banana republic," he continued.
"Can you imagine Trump speaking in the same language toward Turkey and [President Recep Tayyip] Erdogan?" he added.
Israel will destroy Kharg Island, bomb Bandar Abbas next time Iran attacks, Liberman threatens
Liberman also threatened intensified strikes on Iran during the next wave of intensified conflict.
"We need to make clear to the Americans that there is also a new paradigm - the next time Iran launches missiles at Israel, we will destroy Kharg Island and Bandar Abbas Port," he said.
"This is the [regime's] bottleneck. Two points that if you destroy them, Iran falls apart. These are two points - we are no longer firing at sand dunes - these are their most sensitive points," he added.
Liberman: Mossad should move towards a sole mission - topple the Islamic regime
Liberman discussed the significance of the agreement and how he would act following the lessons that Israel must learn.
"First of all, I would give a directive to Mossad. The agency must move to one mission - toppling the [Iranian Islamic] Regime," he said.
This goal should be at the top of the security establishment's priority list, he argued.
"If I were prime minister, I would summon the Mossad director and tell him: 'Don't deal with anything else anymore, except toppling the Iranian regime,'" he continued.
"I know that [toppling the regime] was attempted, but it was a weak attempt. This was not systematic, deep work with the required resources, and lacked an orderly work plan," he said.
IDF needs a Missile Corps, ballistic missiles that could strike anywhere in Iran within 12 minutes, Liberman claims
Liberman also discussed how the IDF should establish a Missile Corps.
"We must reach a completely different paradigm, where our arsenal of ballistic and cruise missiles is at least 20,000 strong," he said.
"You need to understand the difference between a Missile Corps and Air Force. We have the best pilots in the world, but when the Israel Air Force carries out a strike on Iran, it takes hours - preparing crews, armaments, you need to pass through other countries, coordinate with the US military, aircraft, refuelers, a satellite system, and all sorts of additional steps," the former defense minister said.
"With a ballistic missile, you press a button, and within 12 minutes at most, it explodes at any point in Iran," he claimed.
Additionally, Israel needs a stockpile of interceptors and maritime drones, he said.
"The [government] froze the decision I made as defense minister, and now we are paying the price. They also froze my decision to fortify the North - we could have been in a completely different situation," he added.
Liberman: 'Entire security establishment knows Hezbollah heading towards force buildup project'
Israel needs to change strategy vis-à-vis Hezbollah and Lebanon, Liberman said.
"In the last 24 hours in southern Lebanon, Hezbollah fired at our soldiers, and here we have returned to that October 7 conception of containment," he stated.
"This is not a mistake - it is simply Netanyahu's decision to turn Israel and all of us into hostages of his personal and private interests. The entire country is subordinated to this, and it must be stopped," he added.
"We have the ability to act now. The entire security establishment knows Hezbollah is heading towards a force buildup project. We must prevent this," he continued.
"Trump moved the embassy to Jerusalem, recognized the Golan Heights, freed [Gaza] hostages - for three years, this impotent, all-talk, government that is full of empty promises dealt only with declarations, and advancing its private agenda ahead of primaries and elections," he added.
"For three years, there has been no decisive outcome - not against Hamas, not against Hezbollah, not against Iran, and not against the Houthis," he stated.
Liberman believes opposition will oust Netanyahu at upcoming Knesset elections
Liberman also discussed the upcoming Knesset elections slated for later this year and expressed confidence in the opposition's ability to oust Netanyahu's coalition from power.
"There will be a much bigger victory in the elections. There will be a scenario like in Hungary. We will reach a Zionist, statesmanlike coalition, with 63-64 seats," he said.
"I have a clear order of priorities in these elections. First of all, we will replace the government, and afterward become the prime minister. Without the Arab or haredi (ultra-Orthodox) parties, we will reach at least 63 seats," he added.
The Knesset has 120 seats.
Liberman also noted that he is holding talks with various opposition figures, including former prime minister Naftali Bennett and former IDF chief of staff Gadi Eisenkot.
