Ever since the 2006 war, Israel has preferred to contain Hezbollah rather than fight it directly. So determined was Israel to avoid going to war with the terrorist group that it tolerated its significant military buildup. Since 2012, however, the IAF has carried out hundreds of sorties inside Syria aimed at stopping the delivery of advanced weapons to Hezbollah. Israel can continue to delay the arming of Hezbollah, but it has already become quite strong, and a war could occur even if neither side wants it.
