I watched the diplomats leave their seats before Benjamin Netanyahu had properly begun speaking at the United Nations. The scene needed little explanation. Israel’s prime minister stood at one of the world’s most important diplomatic lecterns while scores of delegates walked towards the exits.

Netanyahu did not ignore them. He called those leaving “moral cowards” and continued with a forceful defence of Israel’s military record. He rejected accusations of genocide in Gaza, defended Israel’s attack on Iran and presented his country as fighting enemies that threaten not only Israel but a wider international order. The confrontation inside the hall almost became a miniature version of Israel’s position outside it. Reuters reported the walkout as it happened.

Watching from Karachi, I found myself thinking about an uncomfortable distinction. A country can possess extraordinary military power and still find its diplomatic room narrowing.

Israel has demonstrated the first repeatedly.

The second is becoming harder to dismiss.

A walkout is symbolism. Policy is different.

It would be easy to turn the emptying UN seats into a dramatic declaration that “the world has abandoned Israel.”

That would be inaccurate.

Israel still has powerful international relationships. Its strategic relationship with the United States remains particularly important. Israel also retains substantial commercial and diplomatic ties with Europe and relationships elsewhere that have survived the Gaza war.

So the important question is not whether Israel has suddenly become isolated from the entire international system.

It has not.

The question is whether diplomatic criticism is beginning to migrate from speeches and demonstrations into policy.

There are signs that it is.

Britain, France and Canada announced coordinated steps this month against trade in goods from Israeli settlements in occupied territory. A wider group including Denmark, Finland, Ireland, Norway, Poland, Portugal, Spain and Sweden said they would introduce national restrictions, support European restrictions or actively consider other measures. The UK government’s joint statement sets out the measures.

Britain has gone further. Its government announced an import ban on goods from settlements and plans sanctions against companies and individuals that provide certain services facilitating settlement expansion. London has also maintained suspensions affecting more than 30 arms export licences used by the Israel Defense Forces in Gaza and said it would refuse licences for exports materially contributing to the occupation. The Foreign Secretary’s statement explains the policy.

Those are not diplomats leaving a room.

They are government decisions.

The West Bank is changing the diplomatic equation

Gaza dominates television screens, but the West Bank increasingly shapes foreign policy towards Israel.

The immediate pressure point is settlement expansion.

France, Germany, Italy, the Netherlands, New Zealand, Norway, Sweden and the United Kingdom jointly criticised Israel’s move to advance construction in the E1 area. Their August statement warned that the project would damage the territorial contiguity required for a viable Palestinian state and urged Israel to withdraw the plans. The joint European statement spells out the concern.

The European Union has also imposed additional sanctions on extremist Israeli settlers and organisations accused of serious abuses against Palestinians. In May, the EU added four entities and three individuals to its Global Human Rights Sanctions Regime. The Council of the EU announced the listings.

The language at the United Nations has hardened as well.

On 22 September, UN Secretary-General António Guterres told a high-level meeting that settlement expansion and other developments were eroding the territorial basis for a Palestinian state. He again backed two states based on the pre-1967 lines, consistent with relevant UN resolutions and agreements. His UN statement makes that position explicit.

Israel disputes much of the political and legal framing applied by its critics. Netanyahu’s government argues that international institutions frequently apply double standards to Israel and underestimate the security environment created by Hamas, Iran and other armed adversaries.

That argument has supporters.

It has not stopped the diplomatic pressure from widening.

Netanyahu’s central defence

Netanyahu’s UN argument deserves to be examined on its own terms rather than reduced to the walkout.

He presented Israel as a state facing exceptional security threats. Iran occupied a major part of his address. He defended the decision to attack it and portrayed Tehran’s government as a danger far beyond Israel.

Gaza produced his sharpest confrontation with critics.

Netanyahu called genocide allegations against Israel false and attacked governments and international figures that have adopted them. His position remains that Israel’s military campaign is directed against Hamas rather than the Palestinian population.

The distinction matters.

So does the humanitarian record against which the claim is being judged.

The UN Office for the Coordination of Humanitarian Affairs continues to document severe humanitarian conditions in Gaza. Its September reporting describes civilian deaths, damaged infrastructure and continuing humanitarian needs. OCHA’s 18 September humanitarian report provides the underlying documentation.

None of those facts by themselves determines the legal question of genocide.

That issue must be handled carefully.

The International Court of Justice has issued provisional measures in the case brought by South Africa under the Genocide Convention, but provisional measures are not a final judgment that genocide has occurred. The case therefore should not be described as though the Court has already delivered such a verdict.

Netanyahu rejects the accusation entirely.

The dispute remains both legal and political.

The legal pressure is separate from the political argument

Another institution hangs over Netanyahu’s international travel: the International Criminal Court.

In November 2024, the ICC issued arrest warrants for Netanyahu and then defence minister Yoav Gallant. The chamber said there were reasonable grounds to believe they bore criminal responsibility for alleged war crimes and crimes against humanity during the period considered by the court. The ICC’s announcement records the court’s action.

A warrant is not a conviction.

Israel has rejected the ICC proceedings and challenged the court’s jurisdiction. That distinction must remain explicit because legal allegations are sometimes converted into political verdicts long before judicial proceedings have run their course.

Yet the existence of the warrants creates another unusual feature of Israel’s diplomatic position.

Its prime minister leads a state with formidable military capabilities while simultaneously operating under constraints created by an international criminal proceeding.

Military power cannot make that contradiction disappear.

Military success and political success are different currencies

Israel’s armed forces can destroy a weapons depot. They can strike commanders. Israel can penetrate enemy airspace and employ intelligence capabilities that few states in the region can match.

Diplomacy operates differently.

A missile can eliminate a physical target within minutes. It cannot persuade a foreign parliament.

An air campaign can reduce an adversary’s military capacity. It cannot automatically restore public support in London, Paris or Ottawa.

Military superiority therefore answers only one category of national-security question: Can Israel damage those who threaten it?

Diplomatic power asks another: Can Israel preserve enough international consent to convert battlefield achievements into a sustainable political order?

The distinction is old.

It has rarely been more visible.

Recognition of Palestine changes the argument

The diplomatic environment has also moved because several Western governments have shifted their approach to Palestinian statehood.

France, Britain and Canada said in a joint statement this month that they had recognised the State of Palestine a year earlier. Their September statement presented new action against settlement expansion as part of an effort to preserve the possibility of two states. The joint statement explains their position.

Recognition does not create a functioning Palestinian state.

It does, however, change the diplomatic framework.

Israel increasingly faces governments that no longer treat Palestinian statehood simply as the possible outcome of some future negotiation. They are beginning to treat recognition and economic measures as instruments intended to protect that outcome before territorial changes make it impracticable.

Israel strongly opposes this approach when it believes recognition rewards Palestinian violence or weakens incentives for negotiated settlement.

Here lies the widening gap.

Many Western governments say their measures are intended to preserve Israel alongside a viable Palestinian state.

Netanyahu’s government sees important elements of that pressure as dangerous, unfair or detached from Israel’s security reality.

Both sides increasingly speak the language of protecting Israel’s future while proposing very different routes to get there.

Isolation also has limits

There is another reason to avoid the phrase “Israel is isolated” without qualification.

International politics is not the UN General Assembly.

Security relationships matter. Trade matters. Intelligence cooperation matters. Technology, investment and defence ties often survive political disputes that produce dramatic headlines.

Even Europe has not severed its broader economic relationship with Israel. The EU-Israel Association Agreement remains the institutional foundation of substantial bilateral trade, while settlement products are treated differently under EU preferential rules.

This creates a more complicated picture than either side’s rhetoric suggests.

Israel is not being expelled from the Western political or economic system.

But some governments that once relied mainly on verbal criticism are experimenting with material pressure.

That is the change worth watching.

The empty seats matter because of what may come after them

I return to the UN chamber.

Diplomats stand. Netanyahu watches them leave. Cameras record everything.

On its own, the gesture changes almost nothing.

No border moves because an ambassador walks through a door. No military balance changes. Israel’s aircraft remain powerful, its intelligence services remain capable, and its relationship with Washington cannot be measured by the number of occupied chairs in the General Assembly.

Yet diplomacy often changes slowly before it changes materially.

A condemnation becomes a coordinated statement. A statement becomes a sanction. Governments alter trade rules. Recognition policies shift. Legal exposure complicates official travel.

Not every step leads to the next one.

Enough of them are now appearing, however, to make the pattern difficult to ignore.

Israel has spent decades building one of the Middle East’s strongest military establishments. The wars since October 2023 have demonstrated how far that power can reach.

The question confronting Netanyahu after this week’s UN speech is different.

Military force can create deterrence. It can destroy threats.

It cannot order diplomats back into their seats.
