Britain's Sanctions on Israel: Domestic Politics Dressed Up as Foreign Policy

The quality of the justifications on offer confirms the diagnosis. Foreign Secretary Ed Miliband accused Israel this weekend of blocking the delivery of medicines to Gaza — allegations based, in his own words, on "conversations with people," and which, Israeli officials say, contradict even UN reports. When a country's top diplomat builds sanctions on hearsay, it means the decision came before the evidence.

Another telltale sign: according to diplomatic sources, most if not all of the measures are expected to remain declarations of intent, for lack of a regulatory and legal framework. In other words, London wants the symbolic benefit of sanctioning Israel without bearing the real cost. That is precisely the definition of a domestic political gesture.

Israel's Foreign Minister, Gideon Sa'ar, denounced an attempt to interfere in Israeli elections and promised a vigorous response: Jerusalem is expected to distance itself from the United Kingdom on international agreements concerning Gaza and other diplomatic files.

And this is where the affair goes beyond a bilateral standoff. What Burnham is inaugurating is a dangerous mechanism for every Western democracy: the use of Israel as a bargaining chip in the internal negotiations of left-wing parties. Every conference, every primary, every majority crisis becomes an opportunity for anti-Israel one-upmanship — not because the situation on the ground demands it, but because the radical wing does. The Corbyn precedent showed where this dynamic leads; it took Labour years to recover from it.

All the more so since the United Kingdom is not acting alone: it is pulling the European Union, Australia and Canada along in its wake. One diplomatic source predicts a "cycle of retaliation." For Jews across the diaspora, the lesson is direct: when a European country's domestic politics plays out at Israel's expense, local Jewish communities always end up paying part of the bill — in the climate, in the streets, at the ballot box.
