Read the White Paper of 1939, the british placed themselves at odds with Israel. To make things worse, the situation in europe demanded a new Home for the Jews, as european Jewry had nowhere to run to. While the british were making "peace" with the germans, they were declaring war against all of Israel. And even after the german intentions became apparent and britain sank into the depths of war, the british still refused to grant Jewish refugees entrance into their Homeland.
The british sided with the arabs in Israel, that were led by the mufti of Jerusalem. It is known that this leader had ties with the germans, and that he urged hitler to kill all the Jews, pleading as well with the germans and other arab leaders to help him massacre all the Jews of the middle east.
When the british sided with these people, it became apparent to everyone that they were the enemy of Israel. Therefore the Jews had to wage war against the british.
But Jews have always been a weak and divided people, since they have spread themselves across borders and have lived as minorities amongst the vast majorities. And Jews have consistently betrayed themselves, since they have sworn their loyalties to nearly every foreign land.
If all the Jews lived in one country, then at least they could defend themselves by defending that country. But the Jews have been scattered upon the face of the earth, and thus they have betrayed themselves with every ounce of their strength.
The british policy was almost as destructive as that of the nazis, but it was the germans that did the actual killing. Therefore the germans were Israel's number one enemy. Since england was fighting germany, the Jews were faced with a big dilemma.
By fighting england, they would be helping germany, but by fighting germany they would be helping the british. Yet the Jews of Israel were weak anyhow, and whatever they did they wouldn't have had much of an affect on the greater conflict. Therefore they were best off joining the british in order gain a foothold into europe so that they could rescue their people, and then defy the british so they could attempt to bring their people to Israel. And in Israel they were best suited with a policy of defiance to the british, because england had enough problems to deal with that it should have to invest too much effort in Israel. This gave Israel an advantage, because the british didn't have the strength to rule over Israel.
But the Jews are also foolishly stubborn, in that they stick to their ideals and fight for their opinions even when their thoughts have no merit. And the Jews preserve their loyalties and keep their promises even when this is treacherous to themselves and traitorous to each other. So most of the Jews in Israel and especially in America treated the british as friends and the arabs as equals. Therefore they cooperated with the british even against their own people, leaving their brothers to die and betraying their own neighbors.
Although there were some that characterized the will of Israel, and this sentiment was embodied by the Irgun and Lehi, and sometimes aided by the Haganah. During and after the war (WWII) these people fought to save their brothers in europe and return them to safety in Israel. And after the war, they fought the british, contributing greatly to the liberation of Israel.
Yet these groups were like the Maccabees of earlier days, for while they succeeded in their intentions, they have failed in their success, because the british occupation has been replaced with that of the Americans. They knew Israel had to be liberated, but they did not understand what for.
