The state of Israel did not exist at the time: there was no Jewish country then and therefore no Jewish Embassy. Even if there had been, it is most unlikely that they could have stopped the Holocaust.
They were persecuted, unarmed civilians and were fairly scattered in most of the countries under Nazi rule (except in ghettos).
The killings stopped when the camps were liberated by the Allies. In many cases the SS fled as the Allies approached and left the camps.
because no one objected to their anti-Jewish measures in the thirties, no one took in the Jews when they could and no one tried to stop the Holocaust.
Anne Frank didn't stop the Holocaust. She just made a diary on the thing. The Allies stopped the Holocaust. Anne Frank was just a teenager during the Holocaust. She could not have stopped it. The above answer is correct. See link below for more information.
You can't.

Typically, a ghetto is a part of a city, not necessarily a slum area, occupied by a minority group. The term was first used for the enforced concentration of Jews into specific residential areas in European cities from the Middle Ages, but has now spread to include other ethnic groups in unofficial ghettos, especially black minorities in the USA. Lifestyles within the ghetto differ distinctly from those of the 'host' population and the prejudices of the host confine the sub-group to particular locations. see redlining. Although ghettos are characterized by social disadvantage, most ghettos display a spread of socio-economic groups and the better-off may move to the affluence of the 'gilded ghetto'.

The Holocaust was not the fault of the US! It is sometimes said that the US and their Allies did not do much (or anything) to stop the Holocaust. See the related question.
