A while ago we had a post where some middle east country was using cloud-seeding drones to make every wisp of cloud that drifted overhead dump its water. I could see that being weaponized to deny rainwater to regions in some extremely niche circumstances. Doesn't make 'chemtrails' any less stupid, though.
The article is sort of stupid. Cloud seeding to produce rain has been around since the mid-1940s and is ignored by chemtrail idiots who see weather modification as a weaponized tool that's available to destroy things.
