Here is passage from an Israeli newspaper that refers to IDF sources-which suggests that the attack was intentional- and not due to lack of awareness of the cars belonging to WCK:
« Meanwhile, on Tuesday evening, the Haaretz daily spoke to unnamed military sources who revealed that the cause of the strike was undisciplined, rogue commanders, not a lack of coordination between the IDF and the WCK.
A source in the intelligence branch told Haaretz that the IDF’s Southern Command “knows exactly what the cause of the attack was: in Gaza, everyone does as they please.”
Army regulations require final approvals from division commanders or those above them before strikes can be carried out on sensitive targets such as aid convoys.
But in Gaza, “every commander makes his own rules” and his own interpretation of the rules of engagement, the source told Haaretz, which said it wasn’t clear whether the strikes on the convoy ever received final approval.
The intelligence source noted the IDF decision to establish a new coordination hub between COGAT — which facilitates aid delivery for Israel — and Southern Command but insisted that this wouldn’t solve the problem, as similar centers already exist.
“It has no connection to coordination… You can set up another 20 administrations or war rooms, but if someone doesn’t decide to put an end to the conduct of some of the troops inside Gaza, we’ll see more incidents like this,” the source told Haaretz. »
This does suggest the IDF sources believe an intentional targeting of the WCK by rogue commander within the IDF and therefore not a delusional conclusion?
