Why did Israel deploy Hannibal Directive, allowing killing of own citizens?

A new report says Israel did enact directive, allowing for killings of captives taken by Hamas on October 7.

The Israeli army did deploy its so-called Hannibal Directive, which allows the military to use all necessary force to prevent the capture of soldiers, during the October 7 Hamas-led attacks on Israel, resulting in the loss of both civilian and military lives, an investigation by the Israeli newspaper Haaretz has found.

Here is what we know so far:

For nearly two decades, military censorship kept the directive, also known as the Hannibal Procedure or Hannibal Protocol, under wraps. It allows the Israeli military to use any force necessary to prevent Israeli soldiers from being captured and taken into enemy territory – up to and including action that will lead to those captives’ deaths.

In 1986, Israeli army commanders drew up the doctrine after three soldiers from the infantry Givati Brigade were captured by the Lebanese group Hezbollah.

At that time, Israel occupied a southern region of Lebanon, invading the country in 1982. Hezbollah captured soldiers patrolling this zone, which would remain under Israeli occupation until 2000.
