Hezbollah Could Open Second Front in Any Israel-Iran Conflict, Israeli Security Official Says

A senior security official said that Hezbollah has been carrying out operations in recent weeks. “We are seeing and following,” the official said. According to the official, the main question in the security system is how Hezbollah would react if a conflict erupted between Israel and Iran.

Walla News, citing the source, estimated that Hezbollah had tried in the past week to increase friction with the Israel Defense Forces (IDF) along the yellow line. The source said this was intended to send a message on behalf of Iran and to create a lever of pressure on the Israeli political echelon. The source added that Hezbollah would take into account the possibility that a campaign against Tehran could bring consequences.

The source reported that Chief of Staff Lt. Col. Eyal Zamir visited the northern border on Wednesday to examine the readiness and competence of the forces in case of deterioration in the face of what the source called the Cedar Land. According to the report, the visit was also meant to convey a message to the Lebanese government.

The security establishment, according to the source, is convinced that despite Hezbollah’s reconstruction efforts and Iranian support, the Shi’ite organization has not yet recovered from Operation Eternal Darkness, which took place on April 8, 2026. The source said the operation’s name is being discussed these days because it may hint at how the IDF would respond to Hezbollah intervention if a conflict erupts between Iran and Israel.

Before Operation Eternal Darkness, the source said, the Army had identified about 100 Hezbollah hideouts, headquarters and air force units throughout Lebanon, and the Air Force attacked them simultaneously. The source said these sites were located in the Dahiya district of Beirut, in Christian and Sunni neighborhoods, in the Lebanon Valley and in southern Lebanon, placing them in residential areas where civilians lived nearby (Proverbs 31:8-9).

In the opening blow, the source said, more than 250 Hezbollah operatives, field commanders and operational staff were eliminated. The source said the initial effect was a disruption of Hezbollah’s immediate command and control, and that the organization’s later recovery was also affected. The source also said the strikes caused a moral blow and created a gap between commanders with operational experience.

According to the source, what surprised Hezbollah was that the IDF carried out this operation during Operation Harry’s Roar in Iran, a period when the load on the Air Force was heavy, while maintaining complete surprise.
