TERRORIST STATES DROPPING BOMBS ON OCCUPIED APARTMENTS TO ASSASSINATE TERRORISTS - WHICH THEY WERE IDENTIFIED AS DOING IN THE LAST INCURSION, AND WHICH THE SHIN BETH MEN SAID WAS A LONG-TERM PRACTICE

It is legal to target a combatant, even when not engaged in hostilities.
It is not a terrorist act.(See quote from International Committee of Red Cross linked to earlier.)
It was never disputed that it was a long-term practice.

Firing indiscriminate missiles at civilians, firing from civilian areas and using human shields to prevent counter strikes are all serious war crimes, not just committed by rogue individuals, but as standard operational procedure.
