Who is most connected to the land? 
Him who utterly relies on it.

Hitler loved blood and soil; he vaunted the farmers.

If you are not connected to the land, you will not fight for it.

If you can live everywhere, why would you fight for anywhere? 

We are becoming like the Jews; a people without a place.

Rome conquered Israel.

Cosmopolitan culture; Vienna city culture; that which Hitler hated.

Rome was cosmopolitan and Israel was not. That became false when Israel was conquered and dispersed.

Now, they are back on the land.

And becoming less cosmopolitan as a result?
