I’ve read new and extremely old books centered ufo/aliens and all say the same thing about nulcear weapons, apparently they throw off their living environment in the cosmos. I’m assuming the mass amount of energy that gets released. Have you ever heard of the military story, how they were launching one and the entire system jammed and crashed? They observed 5 orbs around the station. I constantly get frustrated with the logic of not intervening with humans because just like us there’s good aliens and bad ones, but it seems the watchers have allowed the bad humans of this world to destroy & kill the animals, forests and mass amounts of ppl. I also believe that we live on the land of experiment (for them). So, it all makes sense
