Merkel: Nations Must Give Up Sovreignty???

Did Angela Merkel say: "Nation states must today be prepared to give up their sovereignty"???
Zero Hedge says so (warning: that site will give you cancer).
If so, there are 2-3 alarming things about it:

1. That anybody...let alone a world leader...would say it.
2. That I can't find any major news source reporting it.
3. That the left has skipped right over my open borders worry to the elimination of nations outright.

My guess is that this isn't true. Bad translation or something.
