Obviously, it would have helped if the U.S., Britain, Australia and Canada had taken in more refugees from Germany in the 1930s, before the Holocaust began. For an example of this aspect of Holocaust history you can read about the tragedy of the S.S. St. Louis at the related link.
However, the Holocaust could not have been prevented by the United States or any other country (except Germany).
Opinion
It is said that the US and the UK could have tried to bomb rail lines leading to the camps, but it is worth considering a worst case scenario, such as a large air raid that failed to destroy the gas chambers or crematoria but that killed thousands of inmates. It seems that the matter was discussed briefly at the time and that the idea was dismissed.
Opinion
Those with a basic knowledge of air-to-ground warfare in the WWII era will see the impossibility of preventing the Holocaust by bombing the rail lines. Railroad track can be repaired quickly and easily, and even a knocked out train bridge could be repaired by the Gemans in amazing time. The gas chambers were developed at the behest of Heinrich Himmler who after witnessing a mass execution by machine gun demanded something more efficient. Also, few people realize that the first mid-air refueling was done in 1929. The aircraft, named the Question Mark, set a world record for remaining in the air for 150 hours. Only after the war when Communism became the new enemy was it decided that bombers needed an inflight refeuling capability. Bombing surely could have saved some Holocaust victims, but it also would have killed some in the process. Only an invasion of Germany, delayed until 1945 by the squabbling Allies, could have stopped the Holocaust.
Opinion
The British government received frequent reports about the Holocaust from the Polish Home Army and other organizations in Poland from late 1941 onwards. When the first report about regular mass gassings reached London a Foreign Office official who read it wrote in the margin 'Bolshevist Propaganda?' (The document is in the Public Record Office). The U.S. government was also kept informed. Neither government wanted to know. Unfortunately, some of the earliest reports were vague and seemed (or actually were) exaggerated, which did not enhance their credibilty.
Some information obtained was released to the public, and in Britain in late 1942 and early 1943 and there was some discussion in the media about what might be done, and a small campaign to 'do something' got under way. However, it seems that the government saw the issue as a distraction from the war effort and manipulated public discussion in other directions.
There was not that much that the Allies could have done. They could have denounced the Holocaust 'loud and clear' and given it much more publicity. They might have tried to bomb the rail network near the major camps and they could have asked local resistance groups to give a high priority to disrupting the Holocaust. The extermination camps were nearly all in Poland, which was a long way from Allied bomber bases and deep inside German-held territory. A physical rescue by Special Operations would not have been possible. (One needs to have some knowledge of European geography when discussing these matters).
Opinion
Precision bombing of gas chambers and crematoria was not practical. Moreover, the exact location of Auschwitz II (Birkenau) was not known to the Allies till the summer of 1944, following the escape (from Auschwitz) of Vrba and Wetzler who wrote a detailed, high quality report on the camp. It was forwarded to the Allies, who believed its contents and issued a thunderous denunciation ... In the U.S. this report together with another, earlier report was published in English in the U.S. in November 1944.
There are the now famous reconnaissance photographs of Auschwitz I and II (and part of III) which seem to have conveyed nothing at the time to those who analyzed it. (See link)
The Soviet air force was much closer and might have been better placed to bomb that railways near the death camps. As has been pointed out above, precision bombing was difficult as the time. One needs also to consider a worst-case scenario of inaccuate bombing, such as an air raid that killed most of the prisoners but left the gas chambers and crematoria largely undamaged.
Opinion
A Polish courier, Jan Karski, even had two face-to-face meetings with President Roosevelt about conditions in the Warsaw Ghetto and also told him about a feeder camp for Belzec (which he mistook for Belzec itself). When Karski pleaded for immediate intervention, President Roosevelt told him, 'Tell them that the guilty will be punished'.
Opinion
There was no indication prior to WW2 that the Nazis were planning on exterminating the Jews. Persecuting them, certainly, but European countries have a long history of persecuting the Jews (and, to be fair, the US was no innocent here either). The decision to initiate the Holocaust appears to have been an opportunistic one made by Hitler after WW2 began - it's unlikely that had the war NOT started, he would have refrained from beginning a Jewish pogrom at some point, but the systematic killing of Jews started as a side-"benefit" of the German conquests in 1939-41 (from Hitler's point of view).
Also, the idea that an earlier US entry would have stopped Hitler from initiating the Holocaust has no basis in reality. Remember that the Holocaust was conducted even when it conflicted with military necessity - that is, Hitler redirected critically-needed materials and manpower from the military to complete the Holocaust. There's no indication whatsoever that fighting yet another opponent would have halted the Holocaust once it began, as carrying it out became an obsession for Hitler and the SS once it had begun, and no other organization or person inside Germany could have countered this force. And, an early US entrance to the war would NOT have stopped the Holocaust from beginning - the Holocaust was started as a consequence of the military victories of 1939-41. Even if the US entrance had forced Nazi Germany from turning on the USSR in 1941, Germany still controlled the vast majority of territory that held Jews who were killed in the Holocaust.
Opinion
There's no rational scenario where the United States (or, frankly, any other country) could have halted or prevented the Holocaust from starting, since the decision to start was not a rational one to begin with, and the conditions which led to the decision to start were not really preventable - i.e. as soon as Germany finished the early conquests of 1939-40, the conditions to start the Holocaust were met, and there's no real rational basis for assuming that the Germans wouldn't have won the victories they did in 1939-40.
Opinion
To answer the question: there are no rational, let alone realistic, ways that the United States could have preventedthe Holocaust. The single possible route for this would have been to prevent the rise of Hitler in the first place, and that's a task which would have required near omniscience on the part of anyone in the 1920s.
Now, there are a great deal of things that the US could have done to reduce the total body count of the Holocaust, but that's an entirely different issue.
The Holocaust could in fact happen again. Actually, Joseph Stalin caused a "Holocaust" which he called Ethnic Cleansing. Of couse nowadays we have Holocaust rememberence day during which we try to prevent any future Holocaust.Yes it could. If what happened in Rwanda could happen in our enlightened times anything is possible. There was also Bosnia and the killing fields of Cambodia. Sadly, yes it could.
Whipping was one of many punishments. As the Germans had total power over the Jews, they could do what ever they wanted.
They didn't know about the holocaust so they could not do anything about it _______ The Holocaust was well known in Allied countries by late 1942 and was reported in the media and discussed in public. However, in practical terms it is hard to see what could have done.
they could have had a less peace-minded attitude toward the germans and attacked before the blitzkrieg
The US and the other Allies did nothing to increase the number of Holocaust deaths.
Nazi Germany was a totalitarian dictatorship. 'Challenging each other intellectually' was rarely practical. The Holocaust was the kind of topic that generally could only be whispered about furtively; it certainly wasn't a subject that could be discussed openly. Moreover, many Germans knew very little, if anything, about it. It wasn't something that was reported in the media or talked about much by politicians.

they could not do anything because they might not of had enough money or had the skill to do anything
Yes, of course. The Nazis' aim (at that stage) was to kill all Jews that they could lay their hands on: it was genocide.

This is not a simple answer: There were many people tried and punished for their involvement, there were many who died before they could be put on trial and there were many who escaped before they could be brought to trial.The Holocaust was initiated by the Nazis, but as it grew, non Nazis also helped and also non Germans.
the Holocaust was not a movement or a party or anything with members that could have a leader, it was an event. Within the Holocaust there were three main sides, on each of those sides there were many leaders.
The best way to prevent paralysis is to avoid anything that could make you paralyzed. This could compromise your way of living.

The answer is not as clear as one might think. One might argue that the Holocaust started with the rise of Adolf Hitler and the latent anti-Semitism of a large number of Germans. The "final solution," which could be construed as synonymous with the Holocaust, began from the Nazis' desire to rid the territory they controlled of Jews and other "undesirables," and their inability to accomplish this by deportation.
