Ag is obviously the more ridiculous one here (but that's expected whenever ag starts writing about Jewish identity), but it also has to be said...
Its 21st-century incarnation, however, is even more dangerous because it seeks to end all differences between nations, including those between the Jewish nation and other nations (not knowing this is impossible), and is thereby the direct cause of both antisemitism (for why do so many Jews oppose other nations' independence?) and the weakening of the Jewish people through assimilation.
My choice for the Jewish people's future: being a free people in our homeland. Supporting other people's sovereignty in their homelands too. Opposing global institutions threatening the uniqueness of different cultures. Opposing international political integration. Friendly relations between nations based on mutual interests and mutual respect, not treaties and supranational threats.
I don't think "breaking down borders" has to imply "erasing the differences between nations". The very first Persian Empire, which gave the Jews (and numerous other peoples) autonomy, nationhood, peace, and strength, did it by erasing barriers and allowing people to trade freely, while respecting differences in language and worship and such. Enmity in the Middle East is much higher today than it was then (unfortunately), so such a model doesn't particularly work nowadays, but I don't see why it shouldn't for Europe.
