I think these have been memory holed and I'm having a hard time finding them. If any anons can help, I would greatly appreciate it. I'm still trying to find the one of Putin at the conference implying the use of very quiet advanced weapons that could destroy entire continents. There's 1 or 2 more Zhirinovsky ones I can't find.

- Russian scientists can change the gravitational field of the earth and submerge entire continents. (~4m)

- ~2m - secret weapons that can destroy any part of the world in 15 min
Those kinds of weapons wouldn't even be feasible to use offensively anyways. Destroying any significant amount of land, like a continent, would cause actual, extremely devastating climate change, while the planet tries to work itself back out to a stable system. It would be mutually assured destruction, but on everyone on the planet.
Not to mention global-scale, extinction-level earthquakes, most likely.
Large volcanic eruptions, and earthquakes alter the earth axis, and rotation- very slightly, but it does change it. Multiple large scale seismic events, regardless of how they were triggered, could likely cause a global mass extinction event. I would assume that any kind of large enough boom from a weapon would do the same thing.
