Recently Israel bombed a medic and claimed he was a combatant. They had a picture of someone that looked like the man sitting in a military uniform in 2019. However that person was not an active combatant at all.
Their only intelligence to designate him as Hamas was a deep learning match on the picture and the man’s face.
Assuming it was realy the medic in the picture, If any person that was ever affiliated with Hamas is a valid target the same would count for the IDF.
Meaning all Israeli civilians that ever served in the IDF suddenly count as military targets.
