Germany‘s foreign minister threatened unspecified measures against Israel on Tuesday and said Berlin would not export weapons used to break humanitarian law, as he and Chancellor Friedrich Merz delivered their most severe rebuke yet over Gaza.

Germany, along with the United States, had long remained in support of Israel‘s conduct since the October 7, 2023, attacks by Hamas. Its about-turn comes as the European Union is reviewing its Israel policy and Britain, France, and Canada also threatened “concrete actions” over Gaza.

Speaking to broadcaster WDR, Foreign Minister Johann Wadephul warned Germany‘s historic support for Israel must not be instrumentalized, as continued air strikes and shortages of food and medicines had made the situation in Gaza “unbearable.”

Earlier, Merz criticized air strikes on Gaza as no longer justified by the need to fight Hamas and “no longer comprehensible,” in comments at a press conference in Finland.

While not a complete rupture, the shift in tone is significant in a country whose leadership follows a policy of special responsibility for Israel, known as the Staatsraeson, due to the legacy of the Nazi Holocaust.

It also reflects a broader shift in German public opinion.

“Our committed fight against antisemitism and our full support for the right to exist and the security of the state of Israel must not be instrumentalized for the conflict and the warfare currently being waged in the Gaza Strip,” Wadephul said.

“We are now at a point where we have to think very carefully about what further steps to take,” he said, without giving further details.

“Where we see dangers of harm, we will of course intervene and certainly not supply weapons so that there will be further harm,” he said, adding that no new weapons orders were currently under consideration.

The shift in government stance comes after calls among the junior coalition partner, the Social Democrats, to halt arms exports to Israel or else risk what the move’s backers say would be German complicity in war crimes.

Efforts to revive a short-lived ceasefire in Gaza that broke down in March have made little visible progress, although one regional diplomat said talks were still going on in Doha and there remained a chance for a deal.

The German comments are particularly striking given that Merz won elections in February promising to host Israeli Prime Minister Benjamin Netanyahu on German soil in defiance of an arrest warrant by the International Criminal Court (ICC).

“The massive military strikes by the Israelis in the Gaza Strip no longer reveal any logic to me – how they serve the goal of confronting terror,” Merz said in Turku, Finland.

He did not reply to a question about German weapons exports to Israel. Wadephul said arms deliveries were a matter for a security council presided over by Merz, whose meetings are confidential.

The foreign ministry did not immediately reply to a further request for comment on whether Germany‘s next step could include halting weapons shipments.

The chancellor is due to speak to Netanyahu this week.

In his office, Merz has a picture of Zikim beach, where Hamas fighters arrived on boats during their rampage in 2023 that killed around 1,200 people – a picture he had hanging for years previously in his parliamentary office.

Israel‘s ambassador to Berlin, Ron Prosor, acknowledged German concerns on Tuesday but made no commitments.

“When Friedrich Merz raises this criticism of Israel, we listen very carefully because he is a friend,” Prosor told the ZDF broadcaster.

Merz’s comments come on top of a groundswell of opposition to Israel‘s actions. A survey by Civey, published in the Tagesspiegel newspaper this week, showed 51 percemt of Germans opposed weapons exports to Israel.

More broadly, only 36 percent of people in Germany view Israel positively, a survey by the Bertelsmann Foundation found in May, down from 46 percent in the last survey in 2021.

Only a quarter of Germans recognize a special responsibility towards the state of Israel, while 64 percent of Israelis believe Germany has a special obligation, the survey found.
