The medine has killed far more than that number of Jews, both physically and spiritually.
What the Zionists, who unlike the old Yishuv did have power, did during the war killed far more than that number. Spiritually, the medine has killed probably 1/3 of its present population.
Those who died with Shma and Ani Maamin on their lips died al kiddush Hashem. Those who sing that song written by a drunkard who died in New York in the soccer stadium Shabbos morning are desecrating Eretz Yisroel. And anyone who touches the political system there past the municipal level is rolling around in the mud of Sodom.
At worst those who advocated stopping the immigration, and who had no power to do so anyway, were guilty of bad judgement. They rightfully feared for their own lives and for their community, and it happened in 1929. There was not exactly an Internet in those days and no one knew how bad things were getting in Europe.
The baryoinim were just plain reshoei amecho. They were not interested in saving lives of anyone other than their band of oisvorfen so that they could impose their alien ideology, a blend of Communism and the ramblings of a Viennese assimilationist who suffered from a brain infection, on the Jewish land and people.
The real fault lies with FDR ymach shmoi (and whoever ran Canada at the time, the name escapes me), who could have stopped both the Shoah and the medine had he allowed refugees into the US. That would also have ended the Depression, as an influx of talented, industrious individuals would have stimulated the economy. And had it happened, the US would not be facing as much of a challenge as it does today from the Far East.
