well, as long as your thermonuclear nuke's seismic wave signature looks like tremor(s) of an earthquake, planting/burying it near continental plate dividers deep in the ocean should do the trick
Oh yes, we will surely get there eventually. But it probably won't be the giant sky-laser in Alaska that does it. Honestly I don't even understand how people came up with that one. I mean, what is the link between "sky-laser" and "earthquakes", other than "God is mad because we're shining the laser in His eye".
Great, looks like that's done, so that's it for old business. Any new business?
