On Monday, Israeli forces fired on Lebanese Hezbollah fighters who had infiltrated Israel from Lebanon. The incident reflects Hezbollah’s increased interest in carrying out lethal attacks.

Hezbollah media said it suffered no casualties and that the incident was one simply born of Israeli paranoia. The Jerusalem Post reported that there were three to five fighters in the Hezbollah group. Whatever the outcome, the key issue here is why Hezbollah did this in the first place. The group’s leaders knew that there was a very significant risk that their fighters would be engaged and killed. Considering that Israeli forces are not engaged in a military campaign against Hezbollah, the group’s risk-reward calculation here would seem to skew toward not attacking.
