LONDON: The EU must adopt a more assertive posture against Israel over its violations of international law in Gaza, Josep Borrell, the bloc’s former foreign policy chief, has said.

In an article for Foreign Affairs magazine, Borrell argued that the EU has a “duty” to intervene over the humanitarian catastrophe in the Palestinian enclave, The Guardian reported.

Rather than relying on the US to bring an end to the war, Europe must launch its own plan, he said.

The article was co-authored with Kalypso Nicolaidis, a Franco-Greek academic who has advised the EU.

“Europe can no longer afford to linger at the margin. The EU needs a concerted plan,” the two authors said.

“Not only is Europe’s own security at stake, but more important, European history imposes a duty on Europeans to intervene in response to Israel’s violations of international law.

“Europeans cannot stay the hapless fools in this tragic story, dishing out cash with their eyes closed.”

Borrell’s successor, Kaja Kallas, said last week that it was “very clear” Israel had breached its human rights commitments during its war on Gaza.

However, the “concrete question” remains the choice of action EU member states can agree on in response, she added.

Last month, 17 EU member states, in protest against Israel’s blockade of humanitarian aid to Gaza, triggered a review of the bloc’s association agreement with Israel, which covers trade and other cooperation.

Borrell last month accused Tel Aviv of “carrying out the largest ethnic-cleansing operation since the end of the Second World War.”

Europe’s inconsistent response to the humanitarian crisis can be partly explained by the reluctance of some countries — including Germany, Hungary and Austria — to take action against Israel for historical reasons, Borrell and Nicolaidis wrote.

Yet there are ways for other EU member states to take action without requiring a continent-wide consensus, they said, highlighting the EU’s financial leverage and the utility of European programs for Israel, including the Erasmus student exchange scheme.

EU member states could also invoke Article 20 of the EU’s treaty to “allow for at least nine member states to come together to utilize certain foreign policy tools not related to defense,” they wrote.

“Because such an action has never been taken before, those states would have to explore what (it) … would concretely allow them to do,” the Foreign Affairs article said.

The EU has been rendered ineffective in applying pressure due to disunity, the two authors said, arguing that the bloc should act as a powerful mediator in the Middle East.

“Some EU leaders cautiously backed the International Criminal Court’s investigations, while others, such as Austria and Germany, have declined to implement its arrest warrants against Israeli officials,” they wrote.

“And because EU member states, beginning with Germany and Hungary, could not agree on whether to revisit the union’s trade policy with Israel, the EU continues to be Israel’s largest trading partner.

“As a result, the EU, as a bloc, has been largely relegated to the sidelines, divided internally and overshadowed in ceasefire diplomacy by the US and regional actors such as Egypt and Qatar. Shouldn’t the EU also have acted as a mediator?”
