Report them to the IDF? Are you insane? If you came and killed my child I would not report those trying to kill you to the police or army. I would do everything I could to support those trying to kill you.
That's a very bad analogy. It has led you to the wrong conclusion, as bad analogies often do.
A far better analogy: I live in Bellingham, Washington, and my government, the United States Government, stockpiles rockets in my child's school and starts firing them over the border into residential areas of Vancouver, British Columbia, for no good reason. To try to stop the rocket attacks, Canada launches some airstrikes on Bellingham.
In this situation, I would be completely ashamed of my government, the United States Government, and I would be rooting for the Canadians, because I'm a civilized person.
And then if the airstrikes failed to stop the rocket attacks, and Canadian troops arrived in Bellingham, you bet I'd help them find the jerks launching the rockets.
And if the Canadians dropped leaflets begging civilians to evacuate the school before they bomb the rocket-launching site, I would have even more admiration for the Canadians, because that type of concern for civilians is nearly unprecedented in warfare.
And if American leaders called those evacuation warning leaflets "psychological warfare, and urged people to stay put," my disgust for my own government would multiply.
And if my child was killed because a school administrator obeyed the duplicitous order to stay put, would I suddenly lose my grip on logic and rationality, and lash out at the Canadians? Nope. My anger would be entirely directed at the Americans who instigated this conflict.
