I loved it, and to me, there is no "dilemma" there. If Sisko doesn't act, the UFP is in danger of losing the war.
Well the dilemma is at what cost will the Federation be saved. The cost is deceiving an empire into war.
had they not been brought in, the war would have been lost, the UFP would have been conquered, and eventually the Romulan Empire as well.
Sisko was saving both, while at the cost of some deception and a few lives.
As I wrote, Garak's quote sums it up
