Bbc News World: Israel’s perpetual war with Iran may be hard to win with military might alone — 5 stark consequences
On a highway between Tel Aviv and Jerusalem American flags now hang alongside Israeli ones — a visible sign of deeper cooperation as US and Israeli forces carry out strikes since the war began in February. This News World briefing examines why a joint offensive has expanded Israel’s options yet failed so far to resolve regional conflicts, and why a strategy of buffer zones risks trading temporary tactical gains for long-term instability.
News World: Why this matters now
The alliance between Washington and Jerusalem has tangible effects on the ground. Officials say targets are being divided each partner’s capabilities, opening new operational possibilities. Yet political signals from Washington, including talk of winding up the joint offensive, contrast with Israel’s continued occupation of territory in Gaza and Syria and fresh orders to establish a wide “buffer zone” in southern Lebanon. The defence minister’s instruction to take that territory — and to bar roughly 600, 000 people from returning to their homes until northern communities are deemed safe — raises immediate humanitarian and strategic concerns. More than 1, 200 people have been killed in Lebanon, and Iran’s government says almost 2, 000 people have been killed by US-Israeli attacks in Iran since the war began. Those figures frame a conflict that is intensifying rather than being decisively resolved.
Deep analysis: buffer zones, doctrine change and unintended consequences
What lies beneath the headline is a shift in Israel’s security doctrine. Before the Hamas attacks on 7 October 2023, the stated approach was largely one of containment and occasional operations. The context shows that doctrine has moved toward pre-emption: a policy now tied to seizing broad swathes of territory as “deep security belts” beyond Israel’s borders. Prime Minister Netanyahu framed the campaign as inflicting 10 “plagues” on Tehran, explicitly linking those security belts in Gaza, Syria and Lebanon to the wider effort.
Buffer zones are intended as insurance: they give operational flexibility and time, and are described within the region as a hedge against cross-border threats. But establishing such zones carries clear trade-offs. In Lebanon, orders to destroy houses in border villages mirror tactics used in Gaza, multiplying displacement and long-term grievances. The practical effect is that military control replaces political settlement, creating a cycle in which territory seized for security may itself become a source of chronic instability. Even if Washington decides there are no longer relevant Iranian targets and seeks a ceasefire, voices in Israel’s security establishment signal that operations against Hezbollah and other regional opponents will continue.
Expert perspectives and regional implications
Israel’s former National Security Advisor, Tzachi Hangebi, who left office months before the current war, described a longstanding desire for external recognition of the Iranian military threat and welcomed joint efforts to diminish Iran’s capabilities. He said the cooperation with the United States exceeded his most optimistic expectations and that Israel will press forward in Lebanon even if Washington scales back its campaign against Iran. Burcu Ozcelik, a specialist in Middle East strategy at the Royal United Services Institute, called the buffer zone approach an “insurance policy” that both gives Israel flexibility and buys time, linking it explicitly to the wider change in Israel’s doctrine since the October attacks. Those assessments underscore two risks: that military expansion becomes self-perpetuating, and that strategic gains fail to translate into sustainable peace.
Regionally, the combination of US partnership and Israeli territorial control complicates diplomacy. Holding territory in Gaza and Syria while pressing into southern Lebanon increases the potential for prolonged low-intensity conflicts across multiple borders. The immediate human toll and large-scale displacement also create conditions for chronic instability, which could outlast any cessation of active strikes against Iran.
As the campaign evolves, policymakers face a narrow set of choices: seek negotiated political arrangements to replace temporary security belts, accept ongoing military occupation with its attendant costs, or recalibrate operations in response to changing international priorities. Each path carries trade-offs reflected in the casualties and displacements recorded so far.
How will the balance between temporary military advantage and long-term stability shift if external partners alter their engagement, and can Israel convert tactical momentum into the sustainable security its leaders say they want? news world will continue to follow the human and strategic fallout of a war whose outcomes remain uncertain.
