I previously posted regarding 27 IAF pilots in 2003 refusing to fly missions which could endanger civilians in Gaza and the West Bank.
I learned earlier that it was because an Hamas leader was targeted and 15 members of his family were murdered In the attack.
At the time this was considered an outrage in Israel,hence the pilots refusing to fly missions where innocent civilians are killed.
Now its OK to kill 100 civilians if the target is a senior member of Hamas.
