Although ignored for story purposes, the Ancients could have simply shut down the entire Pegasus gate network, activated the Attero device and isolated and eliminated remaining Wraith not destroyed from hyperdrive explosions.

You know the wraith could have been killed in one day if someone remembered to use raid.

any of the ascended ancients could have stopped the thousands of years of culling done by the wraith either by wiping them out, changing the biology of the humans to make them toxic to the wraith, transporting the remaining humans to the milkyway or just by putting them all to sleep and removing the zpms that they stole. Honestly the reason for almost every big bad in all of the SQ series is because the ancients refused to clean up the messes they created.

Honestly, the real loss was the waste of the Asurans. They had self replicating nanites that could build infrastructure and provide manpower faster than their enemy. They didn't need to be murder bots, they needed to be builder and protector bots. Imagine telling the Asurans to strip a whole planet into a fleet of ships and then man them, you leave the command positions open for lanteans and just have the Asurans running around fixing relays and providing security. Its not like they're that vulnerable to most weapons and they're the perfect defence against boarding actions. Can't be stunned, can't be fed on, super strength. If they get blown out into space just come by after and scoop em up and they're fine. The Asurans almost won without the Lanteans there at all starting from basically nothing. Even if the Wraith used the shutdown code it wouldn't matter because the Lanteans could just turn them back on.

I think only the Ori have something to gain in a war with the Wraith. The Ori will have a forever war crusade against evil space vampires to control their worshipers. If the Ori win, HUGE HUGE HUGE propaganda victory over the Ancients. And if they lose, they blame the crusaders for not having enough faith (I don't mean Alliance wise, i mean in general)

The Lanteans fought that war exactly the same way ww2 germany did. Try to overwhelm the enemy, realize their manufacturing capability was 10x what theirs was and that losing was a matter of time, and then sink valuable resources into planning doomed-to-fail superweapon projects.

the larger timeline can get a little fuzzy at times in Stargate

Just realised to horrible scenario of the wraith being able to integrate Asgard cloning tech to clone a never ending food supply

Much more plausibel story is that the other races were very junior to the ancients and caught up in the last 10.000 years

This is an interesting topic.

The Asgard fleet i feel would do better against the Wraith then the Replicators as they are more of a traditional enemy and importantly the Wraith ships are alot easier to blow up, and with the long life span of the Asgard they likey have more combat experience then the Ancients. Also its possible they can use tech like Thor's hammer to protect some worlds from being attacked through the gate.

The Nox could not onyl help in a support role but also disappear human populations from being culled by the Wraith.

The Furlings....can do stuff.

So ine thing to consider is, with the nox hiding humans and many other worlds being protected what are the chances the lack of available 'food' cause infighting among the Wraith.

If the Asgard and Ancients were multi-galactic civilizations, it stands to reason that it's likely that the Nox and Furlings were also at that scale, which means that the Furlings could still be out there. It's too bad that the Agard weren't able to evaluate the Wraith cloning technology. The combined force of the alliance might have had a chance to defeat the Wraith

The ancient don't even need help, they just needed smart writers. All the ancients had to do was send a gate update code to switch off all the gates then use the atterro device and victory was theirs.  In addition, The show never really covers how hard or long it takes to make ZPMs but it doesn't seem the ancients struggle at all to do so, and given how one ZPM drastically enhances earth starships the ancients could have done the same early on in the war and increased their power advantage by 10 fold. The ancient could also just make doom gate satellites like the replicator do to attack Atlantis and that would spare more of their people and resources as ships with crews take way more investment.

The Dakara super-weapon

ancients are probably the dumbest aliens in the local cluster and at the same time the most advanced civ that we know of.

I think they come from a planet called Fur hence their name just like Earthlings or Easterling.

Logistics are a HUGE deal in large scale combat operations.  Even if the Nox refuse to fight and only provide logistical support that could be what turns the tide.  Keeping the supply of food, weapons, ammo, power, and equipment flowing in for the troops to use would be critical.

If/whenever we do actually get a Stargate renewal, I want to see Furlings and I want them to be the most terrifying race imaginable. All claws, teeth, some cross between Xenomorphs and the Gorn.
They can be smart, even friendly, but I want them to look absolutely terrifying. 😂

For those who don't know, one reason the Alliance was formed when the Ancients lived in Pegasus was because it has been stated that the Asgards civilisation was hundreds of thousands years old but not millions. Back to the video, another potential reason the Asgard couldn't help might be that they weren't advanced enough at the time since they have only "scratched the surface" of the Ancients knowledge in their database.

I think the Attero device was the answer.  I agree with others, the Ancients could have effectively shut down the gates by sending out an update to the Pegasus network that prevented them from being able to connect to other stargates.  Without mobility, either by hyperspace or stargates, the Wraith would have been effectively stuck wherever they were, allowing the Ancients to pick them off at their own leisure.  As long as the Wraith weren't allowed to gain access to other hyperdrive tech, they would have been at the mercy of the Ancients.  The Ancients could have enlisted the Asgard to help "mop up" the Wraith, so long as they never allowed any of their ships to be captured (to protect hyperdrive tech), which would have made the eradication of the Wraith that much quicker.

I am more curious to see what would have happened if the Asgard had studied wraith cloning tech.

We know that the ancients were unaware of the cloning, (thanks to the Aurora episode and later the episode where Todd told them the secret.) but imagine if the ancients HAD discovered that secret, and the Asgard came and studied it. Maybe they would have found a way to kill or sabotage the wraith clones, maybe they would have found fixes to their own cloning problems.
We'll never know! 😭
