On humanitarian intervention in general, I guess my view is not unlike the view that was attributed to Gandhi, accurately or not, when he was supposedly asked what he thought about western civilization. He is supposed to have said that he thought it would be a good idea. Similarly, humanitarian intervention would be a good idea, in principle.
There are also people who lived in either side of Germany, but who never had or have any relationship with the other side whether it was former East or former West Germany.
