Assange is alleged to have performed acts that could be construed as attempts to access classified information, beyond merely asking for it--specifically, it is alleged that he assisted Manning with attempting to acquire and decrypt classified documents. That is the heart of the issue--if Assange had merely accepted a document dump from Manning (as he generally did with most other sources), he wouldn't be facing 18 charges today.
