@Walter Hinteler,
Four identified soldiers, who posted on that site -
"Bibi, let us annihilate terrorists." "The battalion demands revenge." - were sentenced to 10 days disciplinary prison.
The IDF said that, "These soldiers were sentenced to several days in prison in light of their actions in violation of military orders. This is a serious incident that is not in line with what is expected of IDF soldiers. Each case that is brought to the commanders' attention will be treated very seriously, as was the cases in question."
Their lawyers will appeal: "The claims that the fighters have raised do not constitute an offense in anyway. These are good fighters and model soldiers."
"Israel sends its soldiers to the front, but does not understand their situation. The conduct seems to be that of someone who wants to look good for hostile foreign officials, some of whom are anti-Semitic and Israel-haters."
