Three years after the devastating October 7, 2023, attack by Hamas militants, Israel continues to face significant security challenges on multiple fronts, with concerns mounting over the potential for renewed violence even as military operations have inflicted heavy damage on Hamas and Hezbollah.

On Israel’s southern border, Israeli Defense Forces (IDF) personnel report daily attempts by Hamas operatives to probe weaknesses along the heavily fortified boundary with Gaza. A recent incident underscored the tactics used: a four-year-old Palestinian child was sent across the so-called Yellow Line separating Gaza from Israeli-controlled territory. According to an Israeli captain stationed in the southern city of Sderot, children, as well as adults disguised in various ways, are often employed to test Israeli defenses. The IDF views such tactics as part of a broader Hamas media strategy aimed at influencing international opinion.

Meanwhile, Israeli forces have uncovered extensive Hezbollah infrastructure beneath civilian areas in southern Lebanon. Underneath a children’s clothing store in Al-Khiam, the IDF discovered tunnels and a large arsenal linked to the Lebanese militant group. Soldiers described finding a command center 25 meters underground used by Hezbollah’s elite Radwan forces, with evidence that dozens of militants had been stationed there. Despite a ceasefire agreement between Israel and Lebanon in June 2025, Israeli officials stress that Hezbollah is preparing for further hostilities and remains intent on significant incursions into Israeli territory, particularly in the Galilee region.

In the West Bank, instability is rising amid renewed militant activity and escalation in violence involving extremist Israeli settlers and Palestinian civilians. Two militants were arrested recently on suspicion of planning attacks on Israeli targets, while Palestinian Authority forces are reportedly expanding their military capabilities. Analysts warn that the increasing tensions, combined with ongoing settler violence, risk triggering a larger-scale uprising or intifada. Palestinian leaders, including Jibril Rajoub of the Fatah faction, have cautioned that unchecked settler actions could provoke a broad reaction.

The porous border between Israel and Jordan also remains a critical security concern, with criminal networks linked to Palestinian militant groups smuggling weapons and drugs into Israel to finance attacks. Israeli officers describe attempts to control the roughly 1,000-kilometer border as an immense challenge, with smuggling continuing despite intensified efforts.

Despite the IDF’s significant gains—including control of nearly 70 percent of Gaza and a 10-kilometer buffer zone in Lebanon—the military acknowledges serious mistakes made before the 2023 massacre, attributed to underestimating Hamas’s capacity and intentions. The IDF has since revised its doctrines to emphasize preemptive disruption of enemy capabilities. However, Israeli officials and analysts emphasize that Hamas and Hezbollah remain actively rearming and planning future operations.

In addition to regional threats, Israel contemplates possible military action against Iran’s nuclear infrastructure. Reports have surfaced of Israeli fighter jets conducting flights near Iranian borders, seen by some as a show of force rather than a direct strike. Prime Minister Benjamin Netanyahu reportedly contemplated a strike on Iranian facilities around mid-October but was dissuaded by former U.S. President Donald Trump. Strategic calculations continue amid mounting tensions with Tehran and its proxies.

Public opinion among Palestinians shows a growing fatigue with militant groups. Polls indicate a majority prefer peaceful negotiations over armed conflict, with significant numbers viewing Hamas as detrimental to Palestinian interests. Still, Hamas leadership maintains its goal to replace Israel with an Islamic state and views past and future attacks as phases in a prolonged jihad, underscoring the ongoing risk of further violence.

Within Israel, the unresolved threat has become a central political issue ahead of upcoming elections. Voters debate leadership accountability for the October 2023 failures and future security strategies. Former IDF Chief of Staff Gadi Eisenkot, leading the opposition Yashar Party, has pledged to dismantle Hamas’s military command within 18 months if elected, while incumbent Prime Minister Netanyahu focuses on maintaining national security against continuing threats.

The IDF, stretched thin and grappling with the psychological toll on soldiers, remains on high alert. Reservists report long, exhausting tours of duty amid persistent militant provocations. Soldiers describe the extensive tunnel networks beneath Gaza and Lebanon, likening the effort to dismantle these arsenals to “emptying the sea with a spoon.” Commanders warn that despite recent military successes, the underlying tensions and preparations by enemies mean another large-scale attack cannot be ruled out.

As one Israeli officer noted, the country’s security landscape has been irrevocably altered by the 2023 attacks, requiring vigilance for years, possibly decades, to prevent a recurrence. Yet uncertainties remain, reflecting the complex and evolving nature of the region’s conflicts.
