There is a huge fucking difference between Sisko's actions and Bush's.
The situations aren't even slightly comparable. The United States does not face an existential threat to its national security and has not faced such a threat since the fall of the Soviet Union. The Republic of Iraq posed no genuine military threat to the United States; what potential for danger it posed could easily have been contained through diplomacy. The decision to invade Iraq was a completely unnecessary decision based upon a lie to the American people that has done more to harm Iraq than to help it.
The Dominion, on the other hand, posed a fundamental threat to the existence of the Federation. The situation between the Dominion and the Federation is more comparable to that between Great Britain and Nazi Germany during World War II than to that between the United States and the Republic of Iraq in 2003, quite frankly. And if tomorrow we were to find out that Winston Churchill (or someone in the Royal Navy) was responsible for perpetuating a fraud upon the United States in order to manipulate it into going to war with the Nazis, guess what? I'd probably say that it was justified in retrospect, because the threat posed by the Nazis and the Axis was an existential threat to the entire world, just like the threat posed by the Dominion was an existential threat to every civilization in the Alpha Quadrant.
I'm in total agreement with your post,
Sci. I should mention that I'm a highly disenfranchised Republican who voted for Bush-Cheney in 2004 (unfortunately).
On the topic. Sisko saved the Federation from the Dominion with his actions in ITPM. Yes, he did turn to the "dark side" of ethics with his subterfuge plans, but it was necessary to save his civilization. Remember, he wasn't initially aware of Garak's secondary plan. He only became aware of it after Garak had carried out the assassination. To reveal the information, after the fact, would have been stupid and suicidal.
Plus, If he hadn't been a part of Garak's assassination plot, someone else would have. I've no doubt in my mind that Section 31 was fully aware of Sisko's subterfuge plans (and fully aware of Garak's assassination plans). They certainly would have carried them out if Sisko and Garak had failed. The costs were simply too high. If the Dominion had succeed, they would have surely slaughtered every person on Earth and several other Federation worlds.
I'm, also, certain that Section 31 has made sure that the Romulans will never discover the truth about the assassination. They have absolutely no morals and they are very through.
