An interesting comparison. If they took in every Jew in Germany they would have been accomplices to an ethnic cleansing but would effectively have prevented an ethnic extermination. So while technically the answer would have been yes in that case it might have been a good thing anyways. But the analogy breaks down here because (1) the UK and USA had strongly antisemitic attitudes at the time and imposed very small quotas on the number of Jews they accepted as refugees and (2) it appears that Israel is not pursuing extermination of Palestinians.
