They talk about the holocaust?
The US Constitution was not affected by Holocaust.
well the Holocaust is important to the worlds history.
no
Nothing specific, the US was fighting a war for most of the time during the Holocaust.
I wonder what you mean by holocaust communities.
yes
The US constitution pre-dated the Holocaust by about 150 years, it did not prevent the Holocaust happening the first time. The Holocaust happened very far away from the USA, whether the US even had a constitution was totally irrelevant.
This question confuses the Holocaust (genocide) with World War 2.
The Holocaust did not reflect US society; it occurred in Eastern Europe, far from US soil, and was perpetrated by a completely different government.
The US Holocaust Memorial Museum is in Washington DC. (There also other Holocaust museums in some other US cities, but the official national museum is the one in Washington DC).
In effect the US did stop the Holocaust. By aiding the Allied victory, in defeating Germany, the Holocaust was stopped. If the US could have stopped it sooner, it is possible that they could have, but at great cost.
