Legally, the picture is clearer than it may first appear. Section 40 of Basic Law: The Government states that going to war, or taking significant military action that could lead to war, requires a decision by the government or by a Security Cabinet authorized to make it. The prime minister cannot make such a decision alone.
The law draws no distinction between a regular government and a caretaker one. Under Section 30 of the Basic Law, an outgoing government continues to fulfill all its functions until a new government is sworn in, so its security powers remain fully intact.
Supreme Court rulings, however, hold that a caretaker government must act with restraint and proportionality because its public legitimacy has changed. When an immediate security need arises that cannot be delayed, the government retains wide latitude. The legal and public questions become far more pressing if it decides on an initiated military move that, operationally, could wait until the political situation is resolved.
At Sunday's meeting, ministers are expected to review their previous decision of October 4, which dealt with raising readiness for attack and surprise-strike scenarios. They will then decide how to proceed on the Iranian front, under American pressure and amid political sensitivity at home.
The tension comes as Washington pursues contacts with Iran. US Vice President JD Vance is considering a direct meeting with Mohsen Rezaei, a senior Iranian security official and secretary of the Supreme National Security Council. The meeting would be part of efforts to advance an agreement to end the war between the countries. President Trump has authorized Vance to move the contacts forward, and Qatar is emerging as a possible venue.
Meanwhile, people around Netanyahu have begun signaling that Likud would not insist on including the Otzma Yehudit party if negotiations open on a unity government. This contrasts with Netanyahu's campaign statements, in which he pledged to stand by his coalition partners, including Itamar Ben Gvir and Bezalel Smotrich. According to the report, Netanyahu's associates have indicated that Ben Gvir would not be part of such a government, partly because of international criticism of his conduct.
