Re: Could the Dominion War have been avoided?
The only way I think the Federation prevents war from the Dominion is by unifying the powers of the Alpha/Beta Quadrant prior to the conflict instead of during it. Obviously this is easier said than done given the nature of distrusting species like the Romulans and a proud military state like Cardassia. I think a unified constant guard assigned to Deep Space Nine patrolling the vicinity of the wormhole could have deferred the war. Sustaining that unified effort would probably be unrealistic though.
Searching for something, a million miles and a ways to go.
