JERUSALEM, April 9 (Reuters) - Even as the U.S. and Iran seek to cement a ceasefire, Israel is seizing more territory from its neighbours in preparation for a long, drawn-out conflict across the Middle East.
Israel's creation of "buffer zones" in Gaza, Syria and now Lebanon reflects a strategic shift after the attacks of October 7, 2023, one that puts the country in a semi-permanent state of war, six Israeli military and defence officials told Reuters.
The
approach also acknowledges a reality the officials said had become increasingly clear after two-and-a-half years of conflict: Iran's clerical leadership, Hezbollah in Lebanon, Hamas in Gaza and militias across the region cannot be eliminated outright.
"Israel's leaders have concluded that they are in a forever war against adversaries who have to be intimidated and even dispersed," said Nathan Brown, of the Carnegie Endowment for International Peace.
The U.S. and Iran agreed on Wednesday to a pause in fighting while they negotiate a broader end to the war, which erupted on February 28. Israel agreed to halt its attacks on Iran but says it will not stop its campaign against Iranian-backed Hezbollah.
Hezbollah joined the war on March 2 by firing rockets at Israel, which then launched a ground invasion of southern Lebanon to clear a buffer zone up to the Litani River - a broad swathe of land that makes up about 8% of Lebanese territory.
Israel has ordered the area's hundreds of thousands of residents to flee and is in the early stages of destroying homes in Shi'ite Muslim villages that it believes have been used by Hezbollah to store weapons or stage attacks.
A senior military official, who requested anonymity to discuss security matters, said the aim was to "clear" an area stretching 5-10 km beyond the border, putting Israeli border towns out of range of Hezbollah rocket-propelled grenade fire.
In some Lebanese villages close to the border, Israeli troops found evidence that nearly 90% of homes contain weapons or equipment linking them to Hezbollah, the official said.
That means the homes are viewed as enemy military positions that must be destroyed, according to the official who said that many southern Lebanese villages sat on hilltops, giving them a direct line of sight into Israeli towns or army positions.
The use of buffer zones represents a new security doctrine that "border communities cannot be protected from the border", according to Assaf Orion, a retired Israeli brigadier general and former head of military strategy.
"Israel no longer waits for the attack to come," he added. "It sees an emerging threat and it attacks it preemptively."
Once the buffer against Hezbollah is secured, Israel will have seized or occupied territory in Lebanon, Syria, the West Bank and the Gaza Strip, where it remains in control of over half the territory after an October ceasefire with Hamas.
Under the ceasefire, Israel is meant to withdraw from all of Gaza as Hamas disarms, though the chances of that happening in the near future appear slim.
"We have established security belts deep beyond our borders," Israeli Prime Minister Benjamin Netanyahu said in a video message released by his office on March 31.
"In Gaza - more than half of the Strip's territory. In Syria, from the Mount Hermon summit until the Yarmuch River. In Lebanon - a vast buffer zone that thwarts the threat of invasion and keeps anti-tank fire a distance away from our communities."
The Lebanese buffer zone plan has yet to be presented to Netanyahu's cabinet, according to a member of the cabinet and two of the officials.
The Israeli military referred queries about the buffer zones to Netanyahu's office, which didn't immediately respond to a request for comment.
DEFENCE MINISTER VOWS TO RAZE VILLAGES
Israel has long held territory beyond its borders, including the occupied West Bank and Gaza, as well as the Golan Heights in southern Syria, territories captured in a 1967 regional war. Israel subsequently annexed the Golan Heights in 1981.
Hundreds of thousands of Israeli settlers now live in the West Bank among about 3 million Palestinians, who seek the territory as the heartland of a future state.
To many displaced Lebanese and Palestinian people, Israel's seizure of their land and destruction of their villages signals further territorial expansion, an interpretation reinforced by rhetoric from some far-right members of Netanyahu's cabinet.
Bezalel Smotrich, Netanyahu's finance minister, said in March that Israel should extend its border up to the Litani River. He has made similar comments about Gaza, saying the territory should be annexed and settled by Israelis.
However, another Israeli military official, who also spoke on the condition of anonymity to discuss operational planning, said the Litani would not mark a new border. Rather, the buffer zone would be monitored with ground troops carrying out raids as needed, without necessarily holding positions along the river.
Israeli Defence Minister Israel Katz likened the devastation exacted on southern Lebanon to the scorched-earth policy used against Hamas in Gaza that saw entire cities depopulated.
"The village homes adjacent to the border, which serve as Hezbollah outposts for all intents and purposes, will be destroyed according to the Rafah and Khan Younis model in Gaza, to remove the treat from Israeli towns," he said on March 31.
Eran Shamir-Borer, an international law expert at the Israel Democracy Institute, said the destruction of civilian property was largely unlawful, with exceptions that include the property being used for a military purpose.
"Sweeping destruction of houses in southern Lebanon that is not based on individual analysis would be unlawful," he added.
ISRAELIS SCEPTICAL OF LONG-TERM PEACE DEALS
Israeli leaders' preference for a strategy led by the use of buffer zones follows decades of failed attempts to secure long-term peace agreements with the Palestinians, Lebanon and Syria.
The Israeli public is deeply sceptical of negotiated peace agreements with the Palestinians. A 2025 poll from the Pew Research Center found that just 21% of Israelis believe Israel and a potential future Palestinian state could coexist peacefully.
A poll from the Tel Aviv-based Institute for National Security Studies found that just 26% of Israelis believed the October ceasefire in Gaza would lead to many years of calm. Most expected a swift resumption of fighting, the poll showed.
Ofer Shelah, a research program director at the institute, said that in the absence of a negotiated peace settlement with Lebanon, having a buffer zone in the north would prevent the threat of attacks or a ground incursion by Hezbollah forces.
But he said the increased personnel needed to patrol fronts across Lebanon, Gaza, Syria and the occupied West Bank would eventually put major strain on the military's forces.
"We would be better off eventually going back to the international border and maintaining a mobile active defences beyond the border, without having outposts there," Shelah added.
