Star Trek is one of my great loves but it certainly does make you an idealist, to be sure. DS9 also had another powerful moment I remember and it was one I learned very well myself when I served. Kira Nerys talked at some length about how if they refused to make any attack that would potentially or even certainly lead to the death of innocent people, the Cardassians would have just made sure every target was shielded by innocent people. At that point, she said they might as well just have given up.
Kira is right and Sisko's speech is foolish.
Using my sci-fi crush as a compelling counter-argument...well played...though I would point out that the Bajorans were the paramilitary organization in that conflict, and the Cardassians never attempted to take the moral high ground.
And just to play devil's advocate on myself, my quote came from the same character who went on to poison an entire world to stop the Maquis (to say nothing of compromising his morals and becoming an accessory to murder in an attempt to tip the balance of the Dominion War). DS9 is filled with instances like this, where the squeaky-clean ideals collide with cold, harsh reality and don't always survive the encounter.
I'm not totally naive. I realize that sometimes the rules have to be bent to accomodate extraordinary situations. However, I believe such actions should only be taken as a last resort, not made commonplace. We should strive to be better than that.
