I kinda have to agree with Myers in the last segment, that's an awfully big promise to make. I agree with it, of course but what if Command, the Council or even the president overrule Dahlgren? That would make a liar out of him.
TLR makes a good point, too. That conversation should have been had in private but I think the other captain should have shown more restraint when he knew he was on an open channel. He was definitely out of line. The crew reaction to Dahlgren's response was brilliant though.
