“Israel is the least safe place for Jews”

Why do antisemites try to use this argument to discredit how much Israel has benefited Jewish life? They say things like “Jews don’t need bomb shelters in other countries”, yet Jews in other countries can’t defend themselves against violence and hatred unlike in Israel. Jews also aren’t being hate crimed for their identity in Israel and don’t always have to live with the looming fear that one day their host country will turn their backs on them like they always have for 2000 years.
