Israel's "Buffer Zone" Strategy—From Tactical Ceasefire to Semi-Permanent War

As the US and Iran ceasefire, Israel has not only failed to stop in Lebanon but has accelerated the implementation of a more far-reaching strategy—establishing "buffer zones" along multiple fronts, shifting toward a semi-permanent state of war.

According to Reuters, six Israeli military and defense officials revealed that Israel is setting up "buffer zones" in Gaza, Syria, and now Lebanon, reflecting a strategic shift after the October 7, 2023 attack. Israeli leaders have already concluded that they are caught in a perpetual war, and that opponents must be deterred or even dispersed.

Nathan Brown of the Carnegie Endowment for International Peace pointed out, "Israeli leaders have concluded that they are caught in a perpetual war, and that opponents must be deterred or even dispersed."

In the Lebanon direction, Israel's ground operation objectives are clear. Senior Israeli military officials disclosed that the goal is to "clear out" areas extending 5 to 10 kilometers beyond the border, to keep Israeli border towns out of Hezbollah rocket and mortar range. Retired Brigadier General Asaf Orian stated that establishing a "buffer zone" represents a new security concept—that "border communities can no longer rely solely on the border line for protection," and that "Israel will no longer wait for attacks to occur; once a threat is detected, it will preemptively strike."

According to reports from Lebanon's Civil Defense, Israeli airstrikes on the 8th caused at least 254 deaths and 1,165 injuries, marking the deadliest single-day toll in Lebanon. The Israel Defense Forces also announced that they have expanded ground operations in southern Lebanon over the past week. The IDF has conducted large-scale airstrikes simultaneously on Beirut, the Bekaa Valley, and southern Lebanon, and destroyed the last bridge connecting southern Lebanon to other parts of the country.

The Israeli military claims to have killed Hezbollah leader Naim Qassem, though Hezbollah has not confirmed this. Lebanese Hezbollah MP Ali Fayyaz called on the Lebanese government to make Israel's adherence to the ceasefire a prerequisite for any subsequent actions, emphasizing that Hezbollah's parliamentary bloc opposes direct negotiations with Israel.

Israeli Prime Minister Netanyahu publicly announced in a video speech that Israel has "established a safety zone deep beyond the border." He listed: "In Gaza—controlling over half the territory; in Syria—from Mount Hermon to the Yarmouk River; in Lebanon—a vast buffer zone to thwart invasion threats and keep anti-tank firepower outside our communities."

This strategy was not solely an Israeli unilateral choice. Officials said that it also acknowledges a growing reality after two and a half years of conflict: that the Iranian clerical leadership, Hezbollah, Hamas in Gaza, and militias across the region cannot be completely eliminated.

However, Israel's "buffer zone" strategy faces multiple risks. On the Lebanon battlefield, the IDF will likely face more intense retaliation, and Iran has already warned that if Israel continues attacks on Lebanon, it will consider it a violation of the ceasefire and may retaliate. Domestically, opposition and concerns also exist. Some media commentaries believe that the US-Iran ceasefire was a golden window for regional de-escalation, but ongoing military actions are dragging Israel into a long-term war, potentially jeopardizing the ceasefire process. Residents and local leaders in northern Israel have previously criticized the government, arguing that only military escalation is currently planned, with no clear plan to allow tens of thousands of civilians to return safely.

As Israel continues ground operations in southern Lebanon and destroys villages and homes, questions about whether these actions violate international law have arisen. Reports indicate that the IDF has begun preliminary destruction of houses in Shia villages, claiming these homes are used by Hezbollah to store weapons or launch attacks. A senior military official revealed that in some border Lebanese villages, nearly 90% of the houses contain weapons or equipment related to Hezbollah, and these homes are considered enemy military positions that must be destroyed.

Once the "buffer zone" against Hezbollah is established, Israel will complete territorial seizure or occupation in Lebanon, Syria, the West Bank, and Gaza. This strategic shift risks prolonging the conflict in the Middle East.
