I'm curious on why you feel that the Swedish prosecutor delayed the case, and kept it in a stalemate even though the Swedish courts have stated (as others have stated here) that Assange does not need to be present in Sweden. If they really wanted to proceed with the case in Sweden, it seems like they could have.

If you believe that this whole thing had nothing to do with extraditing Assange to the US (or using the stalemate to keep him confined to one place), then what was the purpose of waiting for Assange's physical presence in Sweden?
