On Purim of 1973, the Rebbe spoke about the Jews behind the Iron Curtain. His words read as though they were spoken today:

There are Jews currently in a situation where they cannot celebrate Purim openly. However, there are other Jews fortunate enough to have been saved from these circumstances. They can celebrate Purim with full joy and enthusiasm, as instructed by G‑d in His Torah.

When these free Jews celebrate Purim as best they can, they send power, life, and strength to those celebrating Purim behind closed doors and windows, empowering them to persevere and rise above their hardships.

Soon, God will rescue all who are oppressed, captive, and persecuted, men, women, and children, without anyone being hurt, under pleasant circumstances, even joyfully. And they will be prepared for that, because of our celebration here.

By next Purim, those who have been released will dance and celebrate Purim without fear of the nations surrounding them. Just as in the Purim story, their enemies will be in dread of them.

This is something each of us is empowered to do. When Purim is alive for you, when you celebrate it as something happening right now, not just many years ago, you can pull another Jew into your celebration, and another, until all of us, in all “one hundred and twenty-seven” nations of the world (as described in the Megillah) will celebrate Purim next year together in the Holy Land.
