Perhaps to some extent we can agree to disagree then.

I'd have to go back and look at some of the earlier DS9 contacts with the Dominion, but I'm not sure I'd agree about the choice to send the Odyssey as being "brute force." The Dominion claimed to own the whole Gamma Quadrant and had made their displeasure with the wormhole known by destroying a number of colonies on the other side, and when the Odyssey took serious damage and was retreating, the Jem'Hadar destroyed it with a ramming attack to show how far they were willing to go. It wasn't necessary, but it made the point from a political perspective. The Odyssey was sent because it was meant to be a big gun from a political view as well as being capable enough (in theory) to accomplish the mission.
All of which is totally out of character for Starfleet, even assuming the knew somebody like the Dominion was lurking around on the other side of the wormhole. Their mission into the Gamma Quadrant was a rescue operation for Sisko's party, not a "show the flag/gunboat diplomacy" operation against an enemy they know nothing about and have had no prior contact with. The NORMAL procedure in cases like this is for Starfleet to send a small envoy with the intention of de-escalating the situation, trying to ascertain the true nature of the dispute and maybe come up with an agreement that avoids possible hostilities. Yet in this case, Starfleet jumps immediately to "Send a Galaxy class ship to try and intimidate them." Which, incidentally, plays right into the Dominion strategy for this operation, the goals of which were twofold:
a) Plant a Vorta informant in Starfleet in order to feed them misinformation about the Dominion and
b) Give the Federation the impression that they cannot be reasoned with or negotiated with and that the only way to deal with them is all-out war.
It's obvious that the Dominion knew that Sisko and Jake were coming into the Gamma Quadrant, knew when they were coming and why. It's just as obvious they knew the Odyssey was coming, and they knew what destroying the Odyssey would mean. And this is the Dominion we're talking about: If they're in a position to know all of these things, then they're in a position to manipulate circumstances in their favor. And I think that's EXACTLY what they did.
I tend to view Starfleet's actions in the war as being more consistent with those of the U.S. in any of its major wars, including the world wars.
Yes, and is therefore totally inconsistent with the way the
Federation has conducted any of its major wars, or for that matter, sought to
avoid major wars. A similar thing happens in "The Adversary" where a changeling convinces Sisko and his crew to go on a combat patrol along the Tzenkethi border in order to "show the flag" and next thing you know they're getting distress signals indicating that the Tzenkethi are attacking Federation colonies. Here, as before, the Dominion are appealing to Sisko's worst fears and his baser instincts of political superiority. And as with the Odyssey incident, as with the Battle of the Omarian Nebula, as with the attempted assassination of Gowron,
he plays right into their hands.
But look at the lead up to the war: multiple military campaigns and sudden explosions of militaristic thinking in Alpha Quadrant races. The Klingons are conquering again, invading and occupying parts of Cardassia and later even attacking the Federation. The Romulans are reverting back to their old isolationist ways. The Tal'Shiar and the Obsidian Order are engaging in preemptive attacks with fleets of their own. Starfleet becoming heavily militarized even to the point of installing a junta in charge of the Federation.
All of these turned out to be engineered by changelings.
Did you ever stop to think that maybe those are just the things we
know about? How many other self-defeating military strategies did the Dominion whisper into Starfleet's ear just to undermine them from within? My guess is alot more than anyone wants to believe. I even go so far as to speculate that the Founders convinced Starfleet planners to draw resources away from more technically advanced designs like the Soverign and Defiant classes in favor of refitting huge numbers of Mirandas and Excelsiors just to increase their fleet sizes: they convinced Starfleet's top brass that the war was going to be a numbers game, and those officers bought that line of reasoning without realizing that the more advanced starships actually would have turned the tide once their commanders started finding ways to counteract Dominion technology.
The Dominion, unlike the Federation, has a whole military dedicated exclusively to combat and suppressing worlds the Founders control, and an infrastructure designed to support that arm. So I can see them having an advantage for the early phases of the war even if the Feds do everything right.
And yet the Dominion doesn't have a sophisticated core of scientists and engineers to support their military; almost ALL of their technological innovation came from Cardassia. There are indications that their technology and tactics have remained largely unchanged for decades if not centuries. If Starfleet found a way to counteract Dominion weapons and technology, their military superiority would evaporate extremely rapidly.
It's my firm believe that the Dominion knew this and their infiltrators kept Starfleet focussed on more conventional military strategies that they knew wouldn't actually work, partly because Starfleet wasn't particularly GOOD at those kinds of strategies but mainly because the Jem'hadar were specifically trained to DEFEAT those very same tactics. But it didn't completely work: the Federation DID, in the end, adapt to Dominion technology and tactics despite their interference.
