The nuclear weapons theory originated with another twitter post from a guy who wrote they were government drones testing background radiation levels. He said nothing about nukes. The nukes thing came from that unsubstantiated post.
Stepping back, there's a broader issue than the actual question of what these drones are. Unless people followed the evolution of drone warfare over the past two decades, some folks might just now be realizing how vulnerable we are to drones. Drones are cheap to make and hard to detect. Weaponized drones may well become a problem in the future. It's something that has already happened in Ukraine. Russians use drones to terrorize civilians:
"The killer machines, sometimes by the swarm, hover above homes, buzz into buildings and chase people down streets in their cars, riding bicycles or simply on foot. The targets are not soldiers, or tanks, but civilian life…Since mid-July, Kherson and its neighbouring villages along the western side of the Dnipro river have suffered more than 9,500 attacks with small drones, killing at least 37 people and injuring hundreds more…"
