Reuven Kimelman

Nation will not take up sword against nation, neither will they learn, train for war anymore." Because that's the prophetic vision of world peace as inscribed on the UN building.

Rabbi Reuven Kimelman explains more, leads us deeper into the words of the Aleinu.

It begins, "Aleinu l'shabeach la-adon hakol," it is for us to praise the Master of all, and it creates the theological tension.

Is the Master of all, then why is it only Jews who are to praise God? So in the first paragraph, God is yotzer breishit, the theme of Rosh Hashanah, God being the creator of the world, not God the redeemer of Israel.
