Israel was perhaps paying back the Brits for their relentless attacks against their nation from 1947-49 by the Labour government. In any case this was/is between those two nations, not us, but the UK, in league with assorted Arab nations, nearly killed of Israel in its infancy.
Whatever the ins and outs of British/Israeli relations in the late 1940s (and there was as much helping as hindering by the British, albeit usually clumsy) it’s worth remembering that the British (with the French) were the main arms suppliers to Israel in its early years, long before the US took over that role. The 6-day war was won by British Centurion tanks.
