The US Military and probably Russia’s Military, the former Soviet Union, possess weapons that can accomplish this kind of devastation. They should, at least the US has devoted billions to controlling what the DOD calls “earth processes” for 60 years. That would be your basic hurricanes, tornadoes, rain, drought, earthquakes, tsunamis, rogue waves and volcanoes.
Even a medium sized tropical storm, not even big enough to be a hurricane or typhoon, contains as much energy as 10,000 Hiroshima sized Atomic Bombs. If the War Department, later renamed to the Department of Defense to confuse the do-gooders, could control the weather or “Earth Processes” they would control the world. That’s the long held dream of Psychos and control freaks everywhere.
