The problem is created when the world is unable (or unwilling) to differentiate between politics and religion. Orthodox Judaism follows the religious aspect of religion and is thus willing to assimilate into whatever country they have chosen to immigrate to. The political aspect of Zionism, which claims to represent Judaism, is little more than seeking power and control at the cost of the religious Jews that they hide behind.
In a country like the US where political parties are well defined, the citizens of those countries are able to determine who and how their representation is being handled. Zionism isn't that well defined - Zionists claim to be representatives for ALL Jews, yet are ready to throw them to the wolves if their agenda is threatened.
By claiming to represent ALL Jews, they are able to create circumstances where Jews are persecuted and then feed off of the sympathy from a supportive public who defends the Jews.
An example of this is the current Israeli/Palestine conflict. Everyone blames the Palestinians for the conflict when it was started by Israel. Israel will tell you all day long that the Jews are the rightful heirs to "The Promised Land", but they won't define which "Jews" are the ones destined to do the inheriting.
Orthodox Judaism claims that when the Jews were exiled, God told them that they were to remain in exile until the return of the Messiah, who will lead them back to the Promised Land. Around 1895 a Jewish leader named Theodor Herzl decided that he was the Messiah who would lead the Jews back to their homeland and created Zionism for just that purpose. But the "homeland" he was focused on was a Zionist political base in the Middle East - one in which the British thought they could exploit for the mineral rights and easy access to the Suez Canal.
Ever since then, the claims of "establishing a homeland for the Jews" have always emanated from this act of defiance against God. The Balfour Declaration in which Britain "supports" the Zionists goal of establishing a homeland for the Jews was nothing more than a secret agreement with the Zionists to drag the United States into the war.
There is a stipulation in the last paragraph of the document that essentially says that the Zionists are to leave everyone else in the area alone to live in peace. Such a stipulation wouldn't have been needed, except that Britain had already promised Palestine to the Arabs two years before handing it over to the Zionists - and the first order on the Zionist agenda was to take over the entire area - a task that they have almost completed at this point in time.
It's not the "Jews" that everyone hates - it's the Zionists. But when the Zionists promote the concept that Zionism and Judaism are the same things, it's really difficult to know just who to support and who to oppose.
