Just a thought.....and left wing environmental nuts go "ear-muffs" for a moment, you won't approve. Why not nuke the damn hole? I'm not a weapons expert, but wouldn't a nuke, right down the pipe, a mile deep far out into the ocean, do the trick? Any oil in there would be burned up, the rock around it would collapse and melt together probably. Nothing else is working, why not just nuke the damn thing? Sure, some fish would die. Seriously. Send a NAVY sub in. Drop a nuke right on top of the damn hole, blow the shit up, hole is sealed, Obama can take full credit.
