Im not going to say to much on this but will include some graphics i have created and i know you will piece it together.
I will say this though. Venez-WW2-Hitler-South America, at least 1 maybe 2 refitted U boats- Hydrogen Bombs at least 2, once released of East coast will Neutral buoyant allowing them to sit 100ft below the surface. The Tsunami produced will hit the East Coast and knock out the generators that cool the nuke reactors. This will create a disaster like the world has ever seen.
