I think we should use nuclear means to dig the biggest dang hole in that mountain range we can engineer. I mean, take the entire mountain range and reduce it to a very large radioactive hole in the ground that allows nuclear wastewater to flow into iran and irag creating a dead man's zone no living creature can cross. I think we should accomplish this within a one week timeframe so as to preclude any mass exodus from that area.
There will be no collateral damage from the area as there won't be anyone left to complain, and we don't listen to the pakistanis anyway.
First we nuke the periphery and drive any resistance further into the mountain range and then we flatten the mountain range. I don't care what people say about underground tunnels, caverns, holes in the rock, protected facilities, etc., being nuke proof - when you nuke it, it will collapse and when the water floods in there will never, not even ever be anything (or anyone) left to ever worry about.
Think about it, another great inland sea - how nice and convenient for those who remain (living) in the desert. It may be somewhat radioactive for a while, and I won't be buying any beachfront property there but at least we won't have to worry about nuclear terrorism.
Now, I know this is just a hope, and I'm not a presidential contender, but do ya think I can get a Nobel prize for this idea?
