Under mounting pressure, the United Kingdomās new Labour government suspended a total of 30 of the UKās arms licenses to Israel on 2 September.
Itās the first time since the war in Gaza erupted that London has admitted British-supplied weapons and components could be used by Israel in violations of international law.
Foreign Secretary David Lammyās announcement followed earlier reports that Israeli F-35 stealth fighters had bombed a āhumanitarian zoneā in Gaza on 13 July, by Danish news outlet Dagbladet Information and NGO Danwatch.
The UK manufactures and supplies around 15% of the parts for these American-made warplanes. Legally, the UKās own Export Control Act 2002 states that the government must not grant arms licenses if there is even a risk that they will be used in violations.
While some welcomed that step, given it was one of the governmentās first moves as parliament reconvened after a summer recess, many critics warn it hasnāt sufficiently aligned Britain with its humanitarian and legal obligations.
With only 30 out of its total 350 licenses suspended, the move is far from an arms embargo. Crucially, the UK has not suspended the export of F-35 parts, which arguably constitute the UKās biggest contribution to Israelās war.
While Lammy warned that "Israelās actions in Gaza continue to lead to immense loss of civilian life, widespread destruction to civilian infrastructure, and immense suffering,ā he said recently that the arms suspensions were ānot a determination of innocence or guiltā about whether Israel had broken international law.
Mounting legal pressure
Ultimately, the move epitomises newly elected PM Keir Starmer's balancing act, aimed at appeasing both the US and the centrist wing of his party, while addressing pressure over Londonās support for Israel during its assault on Gaza.
This pressure has intensified since Israel killed three British aid workers in Gaza in April, amid concerns from government lawyers and over the UKās complicity in violations of international law in the Gaza war, which has seen around 41,000 Palestinians killed since October 2023.
The new governmentās position is seen as a slight step up from the Conservative government's unequivocal support for Israel.
āThis action should have been taken long ago by the previous government, who failed to take any leadership on the matter,ā Layla Moran, Liberal Democrat MP and foreign affairs & international development spokesperson for the party, told °®Āžµŗ.
Stressing the need to monitor remaining arms licenses, Layla added āwe are concerned that the decision is made solely on risk of use in Gaza and not the West Bankā.
Since 28 August, Israel has conducted its most brutal raids in the West Bank in over two decades, especially in Jenin and Tulkarem. Israel says it is targeting militants, but the significant damage to infrastructure and refugee camps has been by the UN rights body.
Sacha Deshmukh, Amnesty International UKās Chief Executive, told °®Āžµŗ that the decision still has loopholes and that exempting the F-35 fighter jet programme āmisses a clear obligation to hold Israel accountableā for its violations.
He added that āwhile [British] ministers apparently accept that Israel may be committing war crimes in Gaza, it is nevertheless continuing to risk complicity in war crimes, apartheid - and possible genocide - by Israeli forces in Gaza and elsewhere in the Occupied Palestinian Territoriesā.
Starmer's balancing act on Israel
Despite pressure over arms sales, the British government is still keen to maintain strong ties with Israel. Thatās partly due to the governmentās plans to tighten their bilateral trade relations.
After Britain departed from the European Union in 2020, the previous Conservative government pursued a free trade agreement with Israel, of which negotiations began in July 2022 and the fourth round concluded in February 2024. Currently, bilateral UK-Israel ties also span technology, investment, research, and security sectors.
A UK government spokesperson told TNA that āthe bond between Britain and Israel continues to be of vital importanceā.
āOur decision to suspend some arms export licences under one of the most robust arms export regimes in the world is separate to our commitment to deliver our trade negotiations with Israel,ā the spokesperson added.
Crucially, this isnāt the first time Britain has suspended arms sales to Israel. Previous UK governments have also suspended arms exports, including Margaret Thatcher, who imposed an arms and oil embargo on Israel in 1982 over its invasion of Lebanon, and David Cameron, whose government suspended over the 2014 Gaza war.
However, the UKās delayed response in suspending weapons sales - despite the much greater intensity of the current war on Gaza - reflects Britainās growing closeness to Israel, a relationship Starmer still seeks to maintain.
Along with other Western powers including France and the US, Britainās political will to cut ties with Israel has further diminished amid escalating regional tensions with Iran.
While Israel-Iran tensions linger, itās expected that Starmerās government will try to keep making the case to support Israel and its security.
Alignment with the US on Israel
Still, Starmer and Lammy seek to alleviate the mounting pressure on the government to realign with international and humanitarian law.
This was signalled by the resumption of funding to UNRWA - the aid agency for Palestinian refugees - on 19 July, after many of Israelās Western allies suspended aid following Israeli allegations that several UNRWA workers joined the 7 October Hamas attacks. Aid charities and rights groups warned that these cuts would accelerate famine in Gaza.
Additionally, on 26 July, Starmer withdrew Britainās challenge to the International Criminal Court (ICC) regarding Chief Prosecutor Imran Khan KCās attempts to seek arrest warrants for Israeli Prime Minister Benjamin Netanyahu and Defence Minister Yoav Gallant, which the previous government tried to challenge.
These are among the subtle changes expected after Starmer became Prime Minister, even if no radical foreign policy shift were immediately anticipated.
To ensure Britainās continued alignment with Washington, Starmer said that Washington āunderstandsā his decision in an interview with the BBC. Meanwhile, US National Security Advisor John Kirby the UK gave Washington a āheads up,ā showing Starmerās caution about straying from the US.
Fawaz Gerges, Professor of International Relations at the London School of Economics and Political Science (LSE), told °®Āžµŗ that the arms license suspensions are a āminimalist decision designed to signal a policy change, while continuing to align with the Biden administration in their preponderant support for Israelā.
He noted that while the UKās recent arms suspensions alone wouldnāt dent Israelās military capabilities, they, along with the ICC move ācould strengthen the case for suspending weapons sales to Israel in other Western countries, particularly the United States and Germanyā.
Indeed, a significant factor is the added pressure on Israel, as shown by Israeli officialsā angrily accusing the UK of "emboldening" Hamas by suspending arms sales, while Netanyahu refused to meet Lammy after the UK reversed its stance on opposing ICC arrest warrants. This reflects Israel's concerns about losing international support, given its efforts to maintain a positive global image amid the Gaza war.
The prospect of further changes
While Londonās move may bolster further legal challenges to arms sales to Israel in other countries, the UK itself will also face increasing legal pressure.
On 8-10 October, the UK High Court will hear a judicial review lodged by rights groups Al-Haq and the Global Action Legal Network, who have taken over the governmentās arms sales to Israel.
Even so, Starmerās desire to maintain close ties with the US and Israel has limited any broader action, for now. Mounting legal pressure, however, has proven it may be a decisive factor in shaping future military support for Israel.
