Although the US and Britain knew about the genocide of the Jews, they did nothing to help rescue victims or stop it from continuing. Some proposed to bomb the rail system which led trains to Auschwitz.  The proposal was quickly rejected.  The United States as well as many other countries denied the Jews entry into their countries.  The United States argued there was really nothing they could have done to interfere.

Those who survived are still facing long term effects from their experiences many years ago.  Some survivors still to this day have never established families. Others feel guilty wondering why they survived and  millions of others died.  There are many other effects from the holocaust on the survivors. Some include; trouble sleeping, loss of identity, etc. 

This attempt of extintion of a whole group of people was done legally.  For example, look at what happend in Saudi Arabia.  People were being murdered legally for no logical reason. No one is safe because the holocaust could happen anywhere anytime including here in the Unite States.
