Meshaneh makom meshanah mazal applies to a yochid; when klal yisroel has a gezerah, running away won’t help. It will follow us wherever we go, because Hashem’s decrees are inevitable.
In europe, jews tried to avoid the gezerah with shtadlonus
In eretz yisroel, they accepted that romel was 2 days away and turned to the ribono shel olam; the chazon ish said that if the yiden in europe would have done the same, there wouldn’t have been a Holocaust there either.
Hashem is everywhere
