[Clone v.117]

Work my way through the military and politics until I become a nation leader, then, behind the shadows I will cause immense catastrophes (akin to the great depression) and request total power over the country in order to pass any laws as I please so that I can restore everything back to its rightful place.
Then I will name myself Fuhrer of the nation and generate all possible imports of and toxic gas chemicals, after several years of non stop nation wide chemical trading I will send secret commando teams to designated locations around the world.
There they will fuse millions of tonnes of toxic gasses which inevitably fill up the air, destroying trees and life forces whilst also poisoning world water supplies.
This will eventually lead to complete extermination of all life on earth.

Also tape 14854 mega lasers guns and shoot stuff.
