Simply put, I think that nuclear weapons should not be classified as "superweapons" on chaos. Personally I think nukes are too cool, interesting and versatile to be only viable for major factions to use on annihilations. I've had a hard time trying to figure out how powerful turbo lasers when in comparison to nuclear weapons. But some parts of lore both in legends and cannon suggest that simple turbo lasers can be comparable to outright overshadowing modern nuclear arsenals.
In wookiepedia the Acclamator-Class Assault Ship's turbolaser are listed as having 200 GIGATONS per-shot. Which I am going to assume is gigatons of tnt. Which is pretty difficult to even comprehend let alone a volley of 12 shots. (Personally I believe this may have been a written by some lore writer just to fill out information on the ship without really considering how ridonculous 200 gigatons of tnt really is. Plus even the point defense lasers are described as having 6 megatons per shot which is more powerful than pretty much any nuke in current arsenals. So I'm willing to just looks past this as lazy writing.)
But that's in legends, which isn't cannon anymore. However! What is cannon is the Free Virgilian-Class Bunkerbuster. Which are fielded with 3 100 megaton plasma bombs. Which is twice as devastating as the tsar bomba, aka the most powerful nuke ever detonated at around 50-58 megatons. Also Munificent-Class Star Frigates had turbolaser cannons that could allegedly melt an ice moon 1,000 kilometers in diameter. Which is about the size of Texas.
Here's an image of Paris getting nuked by a 100 megaton bomb for reference as simulated by NUKEMAP:

Basically, the power scaling is wonky, I think that nukes should be allowed on the site. Since i would argue that the normal weaponry on warships often equals if not surpasses normal nukes. Plus turbolasers can be shot multiple times. Any chaos character with a fleet could easily turn a continent to slag over the course of an afternoon if they wanted to. (given if there was no real resistance against it). I imagine a counter argument to this would be the fact that turbolasers to leave behind radioactive fallout. Which is fair. But with star wars medical technology it's hard for me to imagine that that would be much of an issue. Plus terraforming exists, to the environmental damage really wouldn't need to last very long. Plus I know folks on this site have used chemical weapons on wide scale before, and those are also weapons of mass destruction.
In conclusion I'd love to be able to use an orion drive starship here on chaos. (or in universe equivalent) But I can't do that if Nukes are being gatekept for major events only. This post is really just me venting about stuff I find a bit arbitrary and desire for an orion drive spaceship (pls giv me orion drive and nukes, thx bye 0w0)
