To destroy intelligence information that had fallen into hostile hands?

The British were hostile to the Jews?

[rmlew]

Yes. They illegally resxtricted Jewish immigration, sending many Jews to their deahts.
The British armed the Arab states, while ensuring that Jews were unarmed. As the British withdrew from Palestine, they opened up their forts to the Arabs.
Had the British-Arab collusion been successful, the Mediteranian would have been red with Jewish blood and Israel would never have existed. From 1925 onwards, the British governments were anti-Zionist.
