Purim at the White House

When the Jews in Shushan went to the party of Achashverosh it was just like going to Purim at the White House today. Rabbi Yaron Reuven says, Haman made a deal with Achashverosh to kill the Jews in Megillat Esther only after Am Yisrael went to the party. HaShem only allows antisemitism to prevent assimilation.
