Nukes could be changed sure, but limiting them is not the way to go. If NK or Seabass want to spend the resources and time buying a huge number of nukes so they can maximize damage, it should be hard to take them down. Seabass has been stockpiling for 83 days at least, his nuke stockpile will be diminished far quicker than that due to firing them off/some being spied away, and that's ok imo.
