Hezbollah Retaliates Against Israel

After Israel recently carried out a series of air strikes against some 5 factions across 3 countries, Hezbollah was ultimately the first to strike back. In this case, the blowback was limited, just a couple of pot shots against the Israeli border at an IDF position. Will this mild carnage be enough to quench the thirst for blood on all sides? Or is this just another escalation on the road to total war?
