It's their own little version of lebensraum, except that they let others do most of their fighting for them.
They used to suck the British into fighting their battles for them back in the 20th century. But right now the only chump they can find is the United states.
The Britts are sorry for their mistakes back then and in the future so will we be sorry for supporting what is just one more European colonist in the ME.
By 1946 they were blowing them (and many non combatants) up, most notoriously in the King David Hotel bombing.
Having the millstone of the 'Palestine Mandate' was not a burden post WW2 Britain wanted, made worse by untrammeled immigration into Palestine after WW2.
While the government accepted that after the Holocaust numbers would increase, they wanted it managed, to avoid setting off a powder keg with the Arabs.
The Foreign Secretary, Ernie Bevin, had some strong arguments with his US counterpart on this, he felt that domestic US political considerations were making the situation worse, with the encouragement of mass Jewish immigration to Palestine.
Yet it was British forces trying to hold the line between Arab and Jew.
The Jewish Terrorist Groups like the Irgun and Stern Gang liked to refer to those troops, essentially peacekeepers, as the 'Nazi British Army'.
Ironic as many of those troops had actually fought the Nazi's unlike those trying to kill them, who had been largely sunning themselves on a Kibbutz for the duration of WW2.
By 1948 the UK had given up on trying to hold the line there, handing it over to the UN.
You have to wonder what would have happened and how attitudes would be different today, had say US troops replaced British ones in Palestine (then would have come under the same attacks from the likes of the Stern Gang, as they would have done, as any 3rd party would be in the way of those groups aims).
