While UNIFIL is supposed to keep terrorists in Lebanon from attacking Israel, in practice the only thing they seem to do in these conflicts is report Israeli troop movements and criticize the IDF.
Foreign Minister Avigdor Liberman called Wednesday for a “harsh and disproportionate response” to a multi-pronged Hezbollah attack that injured seven IDF soldiers on Wednesday.
