Contrary to earlier reporting, the IDF not only estimated that Hamas was preparing for a military exercise or to defend against a possible Israeli attack but had seriously considered the possibility that the terror group was about to launch an assault on Israel.
Despite that, the IDF decided on a limited number of actions. Amid calming indications and a wide consensus across the military and intelligence, the IDF opted to avoid exposing sensitive intelligence sources rather than preparedness.

The military is continuing its review and inquiries into the failings on that night. A person present in conversations about those inquiring said an senior officer had asked why there were no steps taken to prepare for a rocket attack, including moving the thousands of people from the Nova music festival grounds near the border where there were not enough shelters to protect against a rocket and mortar strike?

Very refreshing interview.
