Israel-Lebanon Sea Boundary Row Obstructs Energy Development

A dispute between Israel and Lebanon over their maritime boundary has obstructed energy exploration in the eastern Mediterranean and risks exacerbating tensions between two foes.

After months of deadlock in US-mediated talks, Beirut on Sunday warned against any activity in the disputed area, responding to the arrival of a vessel to develop a field for Israel.

Lebanon has said the field in question, Karish, is in disputed waters. Israel denies this.

Here's what you need to know about the standoff:

What’s at stake?
Gas - potentially a lot of it.

Lebanon and Israel are located in the Levant Basin, where a number of big sub-sea gas fields have been discovered since 2009. Israel already produces and exports gas.

But while Israel has moved ahead, Lebanese hopes of producing energy have been hamstrung by political paralysis.

Lebanon's one and only attempt at drilling - an exploratory well in 2020 - found gas traces but no reservoirs, according to France's Total, part of a consortium with Italy's ENI and Russia's Novatek that was awarded Lebanon's first oil and gas offshore license in 2018.

A gas find would be a major boon for Lebanon, which has been mired in financial crisis since 2019. Eventually, such a discovery could fix Lebanon's long-standing failure to produce adequate electricity for its population.

Israeli officials have previously said they hoped the negotiations would take a short time and that an agreement would strengthen both countries' economies.

But while an agreement could allow both sides to benefit, the issue could risk conflict if unresolved.

Lebanon is home to the heavily armed, Iran-backed Hezbollah, which has fought numerous wars with Israel and has previously warned Israel against drilling in the disputed zone.

What is the dispute over?
Lebanon and Israel are at odds over the boundary separating their exclusive economic zones - an offshore area that a country can claim for resource extraction.

Israel claims the boundary runs further north than Lebanon accepts, while Lebanon claims it runs further south than Israel accepts, leaving a triangle of disputed waters.

After indirect negotiations began in 2020, Lebanon expanded its claim. Israel then did the same.

Karish became part of the zone Lebanon was disputing after Beirut expanded its claim, according to Laury Haytayan, a Lebanese oil and gas expert.

Lebanon has stated that Karish was in the disputed area in a letter to the United Nations, the presidency said on Sunday.

Israel says Karish field, discovered more than a decade ago, is in its exclusive economic zone. Israeli Energy Minister Karin Elharrar said the Lebanese account was "very far from reality".

What does Hezbollah think?
Hezbollah has been a sworn enemy of Israel since it was established in 1982 by Iran's Revolutionary Guards. The group has said the talks are not a sign of peace-making and threatened action if Israel violates Lebanese rights.

But Hezbollah is more deeply involved than ever in Lebanese state affairs, and wants to see Lebanon's offshore energy resources developed. It has not stood in the way of the US-mediated indirect talks and has said it will agree to whatever the government agrees.

Is there a risk of conflict?
The last major war between Israel and Hezbollah in Lebanon was in 2006. The border area has remained largely calm since. Analysts believe both sides want to avoid another conflict.

But Hezbollah leader Hassan Nasrallah said last year Israel was wrong if it thought it could act as it pleased before a solution was reached, and the group would "act accordingly" when it finds that Lebanese oil and gas is in danger.

Following the latest spat, Lebanon said it would invite a US envoy to resume negotiations to prevent any escalation and Israel's defense minister said the matter was a civilian issue to be resolved diplomatically.



Iran-Israel War: A Lifeline for Netanyahu?

The Iran-Israel war has helped strengthen Israeli Prime Minister Benjamin Netanyahu domestically and overseas, just as his grip on power looked vulnerable.

On the eve of launching strikes on Iran, his government looked to be on the verge of collapse, with a drive to conscript ultra-Orthodox Jews threatening to scupper his fragile coalition.

Nearly two years on from Hamas's unprecedented attack in 2023, Netanyahu was under growing domestic criticism for his handling of the war in Gaza, where dozens of hostages remain unaccounted for, said AFP.

Internationally too, he was coming under pressure including from longstanding allies, who since the war with Iran began have gone back to expressing support.

Just days ago, polls were predicting Netanyahu would lose his majority if new elections were held, but now, his fortunes appear to have reversed, and Israelis are seeing in "Bibi" the man of the moment.

– 'Reshape the Middle East' –

For decades, Netanyahu has warned of the risk of a nuclear attack on Israel by Iran -- a fear shared by most Israelis.

Yonatan Freeman, a geopolitics expert at the Hebrew University of Jerusalem, said Netanyahu's argument that the pre-emptive strike on Iran was necessary draws "a lot of public support" and that the prime minister has been "greatly strengthened".

Even the opposition has rallied behind him.

"Prime Minister Benjamin Netanyahu is my political rival, but his decision to strike Iran at this moment in time is the right one," opposition leader Yair Lapid wrote in a Jerusalem Post op-ed.

A poll published Saturday by a conservative Israeli channel showed that 54 percent of respondents expressed confidence in the prime minister.

The public had had time to prepare for the possibility of an offensive against Iran, with Netanyahu repeatedly warning that Israel was fighting for its survival and had an opportunity to "reshape the Middle East."

During tit-for-tat military exchanges last year, Israel launched air raids on targets in Iran in October that are thought to have severely damaged Iranian air defenses.

Israel's then-defense minister Yoav Gallant said the strikes had shifted "the balance of power" and had "weakened" Iran.

"In fact, for the past 20 months, Israelis have been thinking about this (a war with Iran)," said Denis Charbit, a political scientist at Israel's Open University.

Since Hamas's October 7, 2023 attack on Israel, Netanyahu has ordered military action in Gaza, against the Iran-backed Hezbollah group in Lebanon and the Houthis in Yemen, as well as targets in Syria where long-time leader Bashar al-Assad fell in December last year.

"Netanyahu always wants to dominate the agenda, to be the one who reshuffles the deck himself -- not the one who reacts -- and here he is clearly asserting his Churchillian side, which is, incidentally, his model," Charbit said.

"But depending on the outcome and the duration (of the war), everything could change, and Israelis might turn against Bibi and demand answers."

– Silencing critics –

For now, however, people in Israel see the conflict with Iran as a "necessary war," according to Nitzan Perelman, a researcher specialized in Israel at the National Center for Scientific Research (CNRS) in France.

"Public opinion supports this war, just as it has supported previous ones," she added.

"It's very useful for Netanyahu because it silences criticism, both inside the country and abroad."

In the weeks ahead of the Iran strikes, international criticism of Netanyahu and Israel's military had reached unprecedented levels.

After more than 55,000 deaths in Gaza, according to the health ministry in the Hamas-run territory, and a blockade that has produced famine-like conditions there, Israel has faced growing isolation and the risk of sanctions, while Netanyahu himself is the subject of an international arrest warrant for alleged war crimes.

But on Sunday, two days into the war with Iran, the Israeli leader received a phone call from European Commission President Ursula von der Leyen, while Foreign Minister Gideon Saar has held talks with numerous counterparts.

"There's more consensus in Europe in how they see Iran, which is more equal to how Israel sees Iran," explained Freeman from the Hebrew University of Jerusalem.

German Chancellor Friedrich Merz said Tuesday that Israel was doing "the dirty work... for all of us."

The idea that a weakened Iran could lead to regional peace and the emergence of a new Middle East is appealing to the United States and some European countries, according to Freeman.

But for Perelman, "Netanyahu is exploiting the Iranian threat, as he always has."
