Political tension is simmering inside Israel's political circles over latest remarks made by a former spymaster, who said the entity's leaders are guided by "messianic" impulses and are exaggerating the effectiveness of a possible military attack on Iran.

The Israeli cabinet met on Sunday to express anger over the scathing attack launched by former Shin Bet, Israel's domestic security service, director Yuval Diskin on Prime Minister Benjamin Netanyahu and Defense Minister Ehud Barak.

Speaking in a meeting with the residents of Kfar Sava city on Friday, Yuval Diskin said the pair is not worthy of leading the entity as they are making decisions 'based on messianic feelings,' Ha'aretz reported.

"My major problem is that I have no faith in the current leadership, which must lead us in an event on the scale of war with Iran or a regional war," he said.

"I don't believe in either the prime minister or the defense minister. I don't believe in a leadership that makes decisions based on messianic feelings," Diskin added.

The former Shin Bet chief also said, "I don't trust a leadership that relies on messianic leadership. Our two messiahs from Caesarea and from the Akirov Towers are not fit to stand at the helm of the administration."

"Believe me, I have observed them from up close... They are not people who I, on a personal level, trust to lead Israel to an event on that scale and carry it off. These are not people who I would want to have holding the wheel in such an event," Diskin said.

He then slammed Netanyahu and Barak over the Iranian nuclear program, saying they "present the public with a mirage.

"They are misleading the public on the Iran issue. They tell the public that if Israel acts, Iran won't have a nuclear bomb. This is misleading. Actually, many experts say an Israeli attack would accelerate the Iranian nuclear race," said the former Israeli security chief.
