Tygaland is correct. Just because an alliance is neutral doesn't mean they can or should ignore acts of war upon them. For example, I don't believe anyone would have faulted GPA (or did) for fighting back when the Continuum declared war, despite being neutral. Likewise, if TDO considers recruiting from an alliance as an act of war - which, on a personal level, I would not agree with - then there is no breach of neutrality of they were to respond as such.
