My friend trevorpbrennan challanged me to do this, so here you are! Nukes in one command! When you spawn a nuke, nothing will happen. Wait about 8 seconds, and 2 anvils will come out of the sky. This is where you run! When the anvils strike, an explosion happens, and a mushroom cloud will spawn! If you get within 10 blocks of the cloud, you will get withered(radiation). You can get the command here. (NOTE: Very resource intensive! I updated it to instead of spawing particles, it summons tnt!)
