This question confuses the Holocaust (genocide) with World War 2.
They talk about the holocaust?
The U.S. started to help in the Holocaust when the Japs bombed Pearl Harbor.
The U.S. were part of the Allies.
There was no single 'year of the Holocaust' ...
the Holocaust had no 'the Allies' per se, there were alliances like between the escape committees inside camps and the local resistance groups.
the US supplied much hardware for the allies to achieve a military victory over Germany and the Axis powers, thus ending the war and the Holocaust.
No. In fact, 'preventing the Holocaust' was not even a war aim of the Allies. Please also see the related question.

This question confuses the holocaust with World War 2.
No they did not. The reason why Hitler comitted suicide was because he would be held accountable for the holocaust & all the concentration camps. & he was going to be caught by allies, England, France, u.s, russia.. etc. So no, England did not help.
