Hezbollah has threatened Israel’s northern border for decades. Today, however, the nature of this threat has become dire, and the risks of escalation real, as Iran continues supplying Syria and Hezbollah in Lebanon with game-changing weapons to devastate the Israeli homeland.
When the next conflict erupts between Israel and Hezbollah, its scale and intensity will bear little resemblance to those of recent memory. Hezbollah today is highly competent, adaptable and lethal. Its forces have gained invaluable battlefield experience in Syria and amassed more weaponry than 95 percent of the world’s conventional militaries, including at least 120,000 rockets and missiles. This is more than all of Europe’s NATO members combined, and ten times as many as when it last went to war with Israel in 2006.
Especially troubling is Hezbollah’s growing arsenal of powerful long-range precision missiles capable of striking targets throughout Israel. Unlike in recent conflicts, Israel’s missile defenses will be incapable of shielding the nation from such a threat. From the outset of conflict, Hezbollah will be able to sustain a launch rate of more than 3,000 missiles per day – as many as Israel faced in the entire 34-day conflict in 2006.
Despite this quantum leap in its capabilities, Hezbollah is under no illusion about its ability to inflict military defeat on Israel. It will not seek victory in the valleys of Lebanon or the skies over Israel, but in the court of public opinion.
To do so, it will use combat operations to lay the groundwork for an information campaign delegitimizing Israel. Two tactics will be central to Hezbollah’s efforts: first, deliberately attacking Israeli civilian population centers to compel an aggressive response by the Israel Defense Forces (IDF); second, illegally exploiting the presence of Lebanese civilians to shield itself from IDF attack.
Hezbollah will then manipulate the inevitable casualties by relying on widespread misperceptions about the true nature of combat operations and how international law (the law of armed conflict, or LOAC) regulates such operations. It will use the inevitable images of civilian suffering in Lebanon to portray Israel’s lawful operations as immoral and illegal. By weaponizing information and the law, Hezbollah will seek to force Israel to halt its self-defense campaign before the IDF can achieve decisive victory.
This is the increasingly prevalent face of hybrid warfare, where law-abiding militaries confront non-state actors like Hezbollah who blend robust combat capabilities and unlawful tactics with sophisticated information operations. This difficult reality is highlighted in a new report by the Jewish Institute for National Security of America’s (JINSA) Hybrid Warfare Task Force, which examines the significant operational and legal challenges Israel will confront when it is compelled to engage Hezbollah and potentially other regional adversaries including Iran.
A key finding is that Hezbollah’s intentional emplacement of rockets, missiles and other vital military assets in villages and cities throughout Lebanon will increase risks to innocent civilians. To gain strategic advantage, Hezbollah will exploit the common – but erroneous – assumption that Israel, by virtue of attacking these sites, must be acting unlawfully, even when the unfortunate effects of these attacks are rendered unavoidable by Hezbollah’s deliberate and illegal use of human shields.
This dilemma for Israel is further complicated by our expectation that the IDF will be compelled to undertake large-scale, aggressive operations to neutralize as much of Hezbollah’s rocket threat as possible before it is ever employed.
This will include ground operations deep into Lebanon. In addition to their sheer scale, the nature of such operations in towns and villages will magnify the likelihood of collateral damage and civilian casualties. This will also make it much more difficult for the IDF to utilize the extensive and often innovative measures to mitigate risks to civilians that have been commonplace during more limited operations – for example, warnings and providing civilians time to evacuate before an attack.
Despite these challenges, our task force found an IDF fully committed to compliance with the LOAC, knowing full well Hezbollah seeks to exploit this very same commitment. We worry, however, that the nature of a major combined arms operation will contribute to the operational and legal misperceptions that are so adeptly exploited by enemies like Hezbollah, resulting in false condemnation of Israel from the international public, media and many states.
How this story plays out for Israel will have reverberating effects for other professional militaries, including our own. Unless the challenges of such operations become more widely understood, with more credible assessments of legality, morality and legitimacy, others will be incentivized to replicate Hezbollah’s perverse tactics.
Ultimately, this requires a greater appreciation of the realities of combat against hybrid adversaries. It also requires a greater appreciation for how the LOAC strikes a rational balance between civilian protection and military effectiveness. Nowhere will these considerations be more apparent – and more consequential – than in Israel’s next conflict with Hezbollah.
