Yup. Or how about that Manhattan Project — “Hey, this atomic bomb sounds swell, but it’s not going to, say, poison the atmosphere, is it? Oh, it is?? Well, I guess we will just have to invade the home islands the old-fashioned way. Probably lose a million American soldiers and at least 3 times as many Japanese, but it’s worth it to protect the Earth.”
Yeah, Dad’s uncle assembled the Hiroshima and Nagasaki devices. My family was never interested in “Environmental impacts”. Just destroying the enemy.
Whether foreign or domestic, per our oaths.
