Israel has expressed its readiness to engage in any potential escalation between the United States and Iran, despite Washington's 'lack of enthusiasm' for it, while it informed the administration of U.S. President Donald Trump of intelligence information claiming an 'Iranian plot' to assassinate Trump, a development that may put the fragile truce between Washington and Tehran to a new test.

Israeli Prime Minister Benjamin Netanyahu, Defense Minister Israel Katz, and Army Chief of Staff Eyal Zamir said on Thursday that Israel is ready to resume the war on Iran at any moment.

The statements came during a graduation ceremony for Israeli Air Force pilots, where Zamir said the war against Iran 'is not over,' adding that 'new plans are being prepared, and major operations are still expected,' and called for 'readiness,' as reported by The Times of Israel.

Netanyahu, for his part, announced that Israel will remain in the areas it occupies in southern Lebanon, although the Lebanese file is considered one of the most contentious issues in the current truce.

Netanyahu added: 'Iran will not possess nuclear weapons, with or without an agreement,' praising 'U.S. military support,' and considered that 'maintaining Israeli air superiority represents a cornerstone of Israel's security doctrine.'

Katz, for his part, said the Israeli army is 'on alert and ready to resume the war' against Iran, adding that Israel is ready to 'restore air superiority and carry out independent strikes inside Iran to remove threats, for the third time.' He continued: 'If we have to return, we will return with greater force.'

Netanyahu and Trump Call

Netanyahu spoke by phone on Thursday with Trump, and was briefed on U.S. military operations in the region, according to a statement from the Israeli Prime Minister's Office.

The statement said that Netanyahu and Trump agreed to continue coordination between the two countries on various issues.

During the call, Netanyahu said that 'Israel must maintain buffer zones on its borders,' referring to the areas it occupies in southern Lebanon.

Relations between Trump and Netanyahu have seen tension in recent weeks as their positions diverged on continuing attacks on Lebanon and a ceasefire with Iran.

Netanyahu is pushing to continue attacks on Iran and achieve more military objectives, while Trump seeks a way out of the conflict, fearing that its continuation could harm the global economy, after reaching a fragile ceasefire between the United States and Iran last month.

In a development that could represent a new escalation in the confrontation between Washington and Tehran, The Wall Street Journal reported, citing people familiar with the matter, that Israel shared new intelligence information with the United States, claiming a new Iranian plot to assassinate Trump.

Trump addressed threats to his life during his talk to journalists in Ankara, and said he considers himself 'number one on Iran's assassination list.'

He added: 'I'm on all their lists. I saw this morning that I'm on every single one of their lists. So far, I think I've been a little lucky, but maybe it won't last long.'

Washington 'Not Enthusiastic' About Israel's Involvement

Two Israeli sources told CNN on Friday that the Trump administration does not want to involve Israel in the military confrontation with Iran, fearing loss of control over the escalation trajectory.

One of the sources said that Netanyahu 'strongly desires to join the U.S. strikes, but the United States does not want to involve Israel at this time.'

Also, Israeli Channel 12 reported that Tel Aviv is preparing for the possibility that Iran will expand its target range to include Israeli bases used by U.S. aircraft, such as Nevatim and Ramon bases, noting ongoing coordination between the Israeli army and the U.S. Central Command 'CENTCOM.'

It quoted U.S. officials as saying that Washington 'does not seem enthusiastic about bringing Israel back into the fight at this time.'

The report noted that one option under consideration in Washington is reimposing a U.S. naval blockade on Iranian ports, an option that Trump has publicly hinted at, but no final decision has been made yet.

Mediators continue their efforts to prevent a return to all-out war, after the mutual military escalation between Iran and the United States over two days, along with Washington's re-imposition of sanctions on Iranian oil exports, has led to more uncertainty about the future of the fragile truce between the two countries.

Sources from regional mediation countries and a U.S. official told Axios that Qatar, Pakistan, along with Turkey, Egypt, and Saudi Arabia, are intensifying their diplomatic efforts to contain tensions between the United States and Iran, and revive negotiations toward a new nuclear deal, while both sides seek to avoid a return to all-out war.

A U.S. official pointed to diplomatic moves taking place behind the scenes currently aimed at reducing tensions between Washington and Tehran, and explained, as reported by CNN, that Washington is following an approach based on carrying out specific strikes then pausing temporarily, in an attempt to avoid escalation and make room for diplomatic efforts, noting that the United States 'maintains a list of targets to use as leverage.'

A U.S. official told Bloomberg that technical talks between the United States and Iran are still ongoing, despite the military confrontations that threatened to collapse the fragile ceasefire between the two countries. The official added that Washington remains committed to reaching a solution with Iran.
