Israeli Prime Minister Benjamin Netanyahu said on Monday that the current escalation in Lebanon is necessary "to defend our people against Hezbollah."

"We must take out those weapons to pave the way for the safe return of Israel's northern communities to their homes," he said.

Almost a year ago, some 60,000 Israelis had to evacuate their houses when the Iran-backed Hezbollah militia in Lebanon began shelling the border area in northern Israel.

Hezbollah — which is designated as a terrorist organization by several countries, including the US and Germany, while the European Union classifies its armed wing as a terrorist group — has argued that their rockets are in support of Gaza's militant organization Hamas whose fighters along with members of other militant Islamist groups killed around 1,150 people and took some 250 more as hostages on October 7, 2023. Hamas is also designated a terrorist organization by Germany, the US, EU and others. 

According to the Hamas-run Health Ministry in Gaza, at least 41,000 people have been killed as a result of Israel's war against Hamas. 

'Almost full-fledged war'

Meanwhile, the death tally in Lebanon is on the rise. Israel's current attacks, as well as the recent explosions of communications devices and killings of Hezbollah leaders, have claimed the lives of around 500 people and injured thousands more across Lebanon.

The EU's foreign affairs chief, Josep Borrell, has described the situation as "almost full-fledged war."

However, according to Sanam Vakil, director of the Middle East and North Africa Program at the UK-based think tank Chatham House, the current military operation and the dangerous escalation mainly serves as "justification or cover for Israel's seeking to return its displaced citizens to the north."

In her view, however, there are other key factors driving Israel's current attacks on Lebanon.

"Firstly, Israel is trying to delink the Gaza and Hezbollah fronts on its borders," she told DW.

"Israel has not been able to achieve a cease-fire in Gaza, and it has not been able to achieve a peace agreement from Hezbollah because of Gaza," Vakil said.

Meanwhile, the so-called Axis of Resistance, which consists of countries like Iran and multiple militias like Hezbollah, Hamas and the Yemen-based Houthis who consider Israel and the US as their enemies, has been focusing on unifying their forces and pressuring Israel simultaneously since October 7, she added.

Aftermath of the Second Lebanon War

"Secondly, of course, Israel faces a perpetual security threat from Hezbollah in Lebanon," she said.

In 2006, a month-long war between Hezbollah and Israel — called the Second Lebanon War after the First Lebanon War between 1982 and 1985 — ended with the acceptance of the United Nations Resolution 1701.

The conditions were an immediate cease-fire, the deployment of Lebanese troops and UN peacekeepers to southern Lebanon, the withdrawal of the Israel Defense Forces and of Hezbollah from that same area, as well as the disarmament of Hezbollah.

However, Hezbollah did neither retreat to Lebanon's Litani River, which is some 40 kilometers (25 miles) north of the border, nor did the Shiite militia give up its weapons. In the years since, with Iran's support, Hezbollah's military equipment and number of trained fighters has multiplied instead. 

This also fosters fears that Hezbollah fighters could in the future abduct Israeli citizens to their territory.

"Israel is [once more] seeking to force Hezbollah to accept UN Security Council Resolution 1701," Vakil said.

Lebanon war distracts from Gaza war

"Thirdly, with this operation in Lebanon, there is no focus on Gaza," Vakil said.

Almost a year after the war in Gaza began, the international focus has shifted despite ongoing fighting in Gaza and over 90 hostages who remain in Hamas captivity, she pointed out.

"Israel has no strategy for extracting itself from Gaza and it hasn't made it clear what it plans for the day after and it is certainly not talking about an Israeli-Palestinian process," Vakil said.

In her view, the war in Lebanon "is a distraction from the lack of strategy in Gaza."

Ground invasion in Lebanon as potential game changer

Meanwhile, the Israeli population is getting increasingly impatient. Pressure on Netanyahu to reach a cease-fire deal and secure the return hostages is growing.

"From an Israeli point of view, political domestic pressure is very high and is intensifying week per week," Lorenzo Trombetta, a Beirut-based Middle East analyst and consultant for UN agencies, told DW.

He assumes that reaching a consensus has become a key step for the Israeli government. One way to achieve this could be by providing for the security of northern Israel, Trombetta said.

"Only, it is hard to say if Israel will be able to achieve this," he added.

"Who knows if or when an Israeli ground operation will begin? And in what way would Iran react if Hezbollah was on the brink of a total defeat against Israel?" Trombetta asked.
