It's a very poor comparison: Israel isn't regularly shelling Lebanon, nor are they tunneling under the border to conduct cross-border raids, and they don't try and kidnap Israeli soldiers, and so on etc. It is a "cold" border. There is no comparison between this border and the border with Gaza, where people approaching the fence are usually doing so in order to shoot at the IDF, launch mortars or rockets, or to tunnel under the fence to conduct an attack.
