> for a NATO country to expel the US embassy would be a very dramatic act with uncertain consequences.

Absolutely, but when German Interior Minister Hans-Peter Friedrich says "those responsible must be held accountable." I would guess that he means that there will, must be consequences. Closing the embassy is a consequence of last resort, if there is continued intransigence.

Will that happen? that's up to the US government, and possibly not the elected part.
