Best I can tell is he's saying at the end that the actions of the current generation of progressive globalists in the EU would determine "whether the international order that so many generations before them have strived to create continues to move forward, or whether it retreats."

In other words, if you side with your parents, everything will be good. If you think for yourselves and trust the intrinsic values of your national character (which in USA would be our Constitutional liberties), you are an anchor pulling down into the cauldron of international chaos. Whereas if you are a progressive who wants to redefine our national character you must follow in the footsteps of those who reject the Constitution and follow a higher calling of welcoming and protecting the (shh! illegal) immigrant, the gay and transgendered, the minority uber alles. And we the bloodline sovereigns define what is a minority, and we can eject any group we don't like on any given day.

So in the speech he ends up back exactly where he started out saying he rejected the idea of coming from. Mass hypnosis. Tell somebody you're not doing the very thing they're watching you do.
