Foreign minister
On 13 February 2025 Sa'ar spoke with New Zealand Foreign Minister Winston Peters by phone about the ongoing ceasefire between Israel and Hamas and the need for its full implementation including the release of all hostages and the resumption of humanitarian aid to the Palestinians. Sa'ar also thanked New Zealand for designating Hamas and the Houthis as terrorist organisations, and extended an invitation for Peters to visit Israel. On 24 February 2025, he met with the European Union's top diplomat, Kaja Kallas, in Brussels for the first formal talks between Israel and the EU since the Gaza war.
On 15 April 2025, Sa'ar met with UK Foreign Secretary David Lammy in London. The visit to London was not publicized and the meeting with Lammy was described as private. The British Foreign Office said that Lammy and Sa'ar discussed "the ongoing hostage negotiations, protection of aid workers, the need to end the humanitarian blockade of Gaza and stop settlement expansion in the West Bank, and the Iranian nuclear issue". His visit was met with outrage by critics of Israel in the UK. British MP Zarah Sultana called his visit "a direct affront to both international law and the Palestinian people enduring genocide, military occupation and apartheid under his government". The Hind Rajab Foundation and International Centre of Justice for Palestinians wrote to the UK attorney general to apply for an arrest warrant for Sa'ar. The request claimed that Sa'ar was responsible for the attack on Kamal Adwan hospital and the detention and torture of Hussam Abu Safiya. The British attorney general rejected the request for an arrest warrant. The National reported that Sa'ar had planned to leave the UK early to avoid a potential arrest, but Lammy had privately assured him that the government would protect him from prosecution. Prime Minister Keir Starmer denied that he had been involved in the decision to deny the arrest warrant.
On 15 July 2025, the European Union's chief diplomat, Kaja Kallas, along with the foreign ministers of EU member states, agreed not to pursue any actions against Israel concerning alleged war crimes in Gaza and settler violence in the West Bank. The proposed sanctions against Israel included suspending the EU-Israel Association Agreement, suspending visa-free travel, or blocking imports from Israeli settlements. Sa'ar welcomed the decision, saying that Israel had achieved "an important diplomatic feat by managing to push back the obsessive attempts by several European Union countries to impose sanctions on Israel."
Under Sa'ar's tenure, Israel became the first country to recognize Somaliland, a breakaway region of Somalia, as an independent state, in December 2025. In January 2026, he visited the territory and met with president Abdirahman Mohamed Abdullahi.
In January 2026, Sa'ar expressed strong support for the U.S. military action in Venezuela, which resulted in the capture of President Nicolás Maduro.
On 8 January 2026, Sa'ar issued a warning regarding the Aleppo clashes carried out by the Syrian transitional government, describing the situation as "dangerous and alarming." He emphasized that the international community in general and the West in particular have a moral obligation to the Kurds, who have bravely and successfully fought against ISIS.
In January 2026, Sa'ar strongly condemned the Iranian regime's crackdown on ongoing anti-government protests, describing it as a "massacre" of its own citizens. Sa'ar urged the European Union to designate the Islamic Revolutionary Guard Corps (IRGC) as a terrorist organization.
In July 2026, following comments by Turkish Foreign Minister Hakan Fidan in which Fidan said of Israel “These people have become a burden that humanity can no longer bear. The human conscience cannot bear it, political systems cannot sustain it, and economic systems cannot sustain it either", Sa'ar condemned Fidan's statement as a “clear call for genocide” and said in a joint statement with Rwandan Minister of Foreign Affairs and International Cooperation Olivier Nduhungirehe that "The Jewish people know all too well what happens when such words are allowed to go unanswered. The first step on the road to genocide is dehumanization."
In September 2026, the Hind Rajab Foundation filed a criminal complaint in Slovenia against Sa'ar, who is scheduled to visit the country to open the Israeli Embassy, accusing him of war crimes, genocide, and torture.
