"We have to acknowledge it, there were plenty of failures and the public sees them and understands it," Diskin said during a Shin Bet ceremony Tuesday. His harsh remarks were reported by Channel 2 news during Wednesday's evening newscast.
Diskin, who joined others who in recent days voiced their criticism over the government's conduct during the war, said that he thinks people like him, who are part of the government, should be speaking up.
"This is not the time to cover up and we need to tell the truth," he said. "No doubt, the north was abandoned and someone should provide explanations and take responsibility."
'Philadelphi route is breached'
However, the Shin Bet chief chose to end his speech on an optimistic note and told the audience about bereaved families and wounded Israelis that met and encouraged him. Diskin also praised "the people's strength and the strength of the Israeli home front."
Earlier this week, Diskin warned government ministers that the strengthening of terror groups in the Gaza Strip is a strategic problem that could result in a Lebanon-like reality in several years.
The Shin Bet director warned that the Philadelphi route is breached and that several tons of explosives and hundreds of weapons have been brought into Gaza recently.
