When is a war crime not a war crime? When, according to British officials, that war crime has been given a makeover as a "charitable act".

The British state is being asked to account for its financial and moral support for a UK organisation accused of complicity in the ethnic cleansing of hundreds of thousands of Palestinians from their homeland. So far, it appears determined to evade answering those questions.

The target of the campaign is the Jewish National Fund UK (JNF UK), which describes itself as "Britain's oldest Israel charity". Noting its role in "building Israel for over a century", the organisation boasts: "Every penny raised by JNF UK is sent to a project in Israel."

In fact, donations to JNF UK were used to buy some of the 250 million trees planted across Israel since 1948, the year when 750,000 Palestinians were forced out at gunpoint from their homes by the new Israeli army. Those expulsions were an event Palestinians call their Nakba, or "catastrophe".
