"There has never been a political disaster like this in our entire history. Israel was not even close to the table when decisions were made concerning the core of our national security," the country's main opposition leader Yair Lapid wrote on X.
"The army carried out everything that was asked of it, and the public showed remarkable resilience, but Netanyahu failed politically, failed strategically, and did not achieve any of the goals he himself set."
Netanyahu had set the elimination or at least severe degradation of Iran's nuclear programme as a central goal of the war.
He also called for neutralising Iran's ballistic missile capabilities, weakening or potentially toppling the Iranian regime, and curbing Tehran's regional influence by targeting its network of allied groups.
"It will take us years to repair the political and strategic damage that Netanyahu caused due to arrogance, negligence, and lack of strategic planning," Lapid said.
The United States and Iran agreed to a two-week ceasefire in an 11th-hour bid to avert all-out destruction of Iran threatened by US President Donald Trump.
Israel said it supported Trump's decision to suspend his bombing of Iran, but maintained the ceasefire "does not include Lebanon".
Moreover, the head of the left-wing Democrats party, Yair Golan, called the ceasefire a "strategic failure" by Netanyahu.
"He promised a historic victory and security for generations, and in practice, we got one of the most severe strategic failures Israel has ever known," Golan said on X.
"It's a total failure that endangers Israel's security for years to come."
Member of parliament and opposition figure Avigdor Liberman also denounced the truce, saying it gave the Iranian regime "an opportunity to regroup".
More reaction was expected to come later on Wednesday after the end of the Jewish holiday of Passover.
