The episode only works if the Romulans find out the truth after the Dominion War and declare war on the Federation. The writers wimped out by not showing that.
How can you justify that statement?
. Are you saying that the crux of drama is invalid with out a follow up ep, or just that it doesn't "work" for you
Personally, I think a big reveal by either Starfleet HQ or the Romulans knowing, would lessen the drama, the strength is in the ambiguity and moral struggle.
