While I agree with a character driven series, I don't agree with not showing the war.
The only reason that Valdore's plan was stopped was that the Aenar decided to revolt. Robot ships could have been used and fit into the not seeing or hearing from either side.
I'm thinking that events during the war could be seen during some episodes, showing what the crew did and the impact it had on them. But since we already had a war in DS9, another in ENT would be a little overkill, especially with the aftermath being great story fodder.
