Fine, but what, precisely, do they intend to talk about? Iran will have nuclear weapons. If the only issue is what the Germans will give them anyway, then why negotiate at all?
"Fine, but what, precisely, do they intend to talk about? Iran will have nuclear weapons." particularily if germany sells them more technology.
If they all continue to talk, sure as tomorrow morning Iran will be fully armed. Then, possibly, there will be no tomorrow.
Germany will negotiate the precise nature of dhimmi status and how many will be permitted dhimmitude.
