More than nine months into its war with Hamas in the Gaza Strip, Israel now appears closer than ever to a second, even larger war with Hezbollah on its northern border. In June, the Israel Defense Forces announced that plans for a full-scale attack in southern Lebanon had been approved. And in mid-July, Hezbollah leader Hassan Nasrallah said that the Iranian-backed Shiite group was prepared to broaden its rocket attacks to a wider range of Israeli towns.
Although the possibility has received relatively little scrutiny in the international media, a full-scale war between Israel and Hezbollah would have consequences that dwarf the current Gaza conflict. A major Israeli air and ground assault against Hezbollah, the most heavily armed group in the Middle East, would likely cause turmoil across the entire region, and could prove particularly destabilizing as the United States enters a crucial stage of its presidential election season. It is also far from clear that such a war could be ended quickly, or that there is a clear path to a decisive victory.
The implications for Israel itself could be stark. Although Israeli air defense systems have been extremely successful thus far against missile attacks from Gaza, Lebanon, Iran, and Yemen, a total war with Hezbollah would be a whole different ballgame. According to Israeli intelligence estimates, Hezbollah’s weapons stockpile is more than seven times as large as Hamas’s and includes far more lethal weapons. Along with hundreds of attack drones, it includes some 130,000–150,000 rockets and missiles, including hundreds of ballistic missiles that could reach targets in Tel Aviv and even further south—indeed, every point in the country.
