Every IDF soldier is drilled in open-fire restrictions that give encroaching Palestinians benefit of the doubt until they brandish a weapon or make a serious threat. Soldiers are also exposed to stories of incarceration until court-martial for those who open fire until, in effect, they prove their innocence (it's military justice). I know of 2 IDF soldiers who opened fire on Palestinians for no morally valid reason whatsoever, and no sensible Israeli justifies what they did. As for the IDF at large, I, too, don't give it 99% support. I give it 100%.
