Iran-backed Hezbollah is reportedly rebuilding its military strength along Israel’s northern border, raising concerns among experts about the potential for renewed conflict. This development comes a year after the United States helped mediate a ceasefire between the two sides.

On Wednesday, IDF spokesperson Nadav Shoshani accused Hezbollah of “blatantly violating the ceasefire agreement.” Shoshani also shared a video that purportedly shows the group rearming, alleging that Hezbollah is “working to restore its capabilities in the village of Beit Lif.”

Critics contend that the U.N. peacekeeping force, UNIFIL, is failing to enforce its mandate to disarm Hezbollah. Meanwhile, the Lebanese Armed Forces are perceived to be acting too slowly, prompting Israel to continue its frequent strikes against Hezbollah’s infrastructure and personnel in Lebanon.

Sarit Zehavi, an Israeli security expert on Hezbollah from the Israel Alma Research and Education Center, shared with Fox News Digital that Hezbollah currently lacks the “capability to launch an October-style invasion.” She noted that while they possessed this ability prior to October 7, 2023, the group can now only deploy a limited number of operatives, adding, “I hope it will take a few years for them to regain those capabilities.”

Fox News Digital had previously reported on Hezbollah’s strategy to invade northern Israel and execute a scorched-earth campaign against the nation.

A day after the Iran-backed Hamas invaded Israel on Oct. 7, 2023, and massacred over 1,200 people, Hezbollah launched missile attacks against Israel.

Zehavi said, “Both the IDF and Hezbollah are very active. The IDF is very active to stop the rehabilitation of Hezbollah and Hezbollah is very active in rebuilding. Hezbollah learned lessons. It has been more problematic to smuggle weapons to Lebanon from Syria. It is happening. But the Syrians intercepted weapons.”

She noted that the “Syrian regime is willing to fight Hezbollah to fight weapons smuggling. Hezbollah is relying more on manufacturing rockets.”

Zehavi, who lives in northern Israel, said that “almost half of Israeli attacks on Hezbollah are south of the Litani river. We see a lot of investment from Hezbollah in drones, short-range rockets, mortars and anti-tank missiles.”

On Tuesday in Germany, prosecutors started a trial against an alleged Hezbollah member running “an extensive drone program for some time.”

The German Federal Prosecutor’s Office said the suspected Hezbollah operative Fadel Z joined Hezbollah more than 10 years ago and worked as a “foreign operator” for the group’s drone program in 2022 in Spain and Germany.

Zehavi said it suffered a defeat of its leadership via the Mossad pager attack on its commanders. However, she added, “Iran immediately provided oxygen to Hezbollah for treatment to help revive Hezbollah.”

She outlined Israel’s main defense strategy against Hezbollah. First, the IDF has positions in Syria and Lebanon. “We cannot have civilians on the front line. The IDF is on top of hills in Israel and Lebanon and can see everything and can respond quickly to terrorist activities. This means when an Israeli woman opens her window and used to see a Hezbollah flag, she now sees an Israeli flag. This gives her a sense of security. This was not present before Oct. 7.

She estimates Hezbollah has 50,000 terrorists and 50,000 reservists. “We killed a few thousand terrorists.”

The IDF made dramatic advances in eradicating Hezbollah’s missile arsenal. “We degraded 80%” of the rockets, Zehavi said, noting the elimination of sizable numbers of Hezbollah’s long-range and highly accurate missiles.

Edy Cohen, a Lebanese-born Israeli scholar of Hezbollah, said, “There is no lack of arms for Hezbollah in Beirut and Lebanon. Lately, we saw many reports that Hezbollah received arms from Syria and Iran is trying to send arms by civilian Iranian airplanes.”

He said there is enormous pressure on Hezbollah and every week Israel is killing Hezbollah operative. The Shiite community in Lebanon wants Hezbollah to retaliate against Israel, said Cohen, adding, “For the Shiite community Hezbollah is the state.”

Cohen said the IDF is gathering intelligence information about Hezbollah’s arsenal and attacking almost every day its leaders and operatives.

He warned that because “Hezbollah said it will not disarm its militia … the big war will come.”

Fox News Digital reported in early November that Trump’s U.S. Ambassador to Turkey, Thomas Barrack, who also serves as envoy to Syria, said that Lebanon is a “failed state,” because of its “paralyzed government.”

He also noted that Hezbollah retains 40,000 fighters and between 15,000 and 20,000 rockets and missiles, noting the terror group pays its militia $2,200 per month, whereas the Lebanese Armed Forces soldiers earn $275 a month and have inferior equipment as well.
