Neko, considering this specific set of circumstances, I would consider a nuclear option insane, yes. Ideas with technical merit created this problem in the first place.
Also, we are not discussing the merits of drilling for oil here but what needs to be done and I was giving a reason why such a method could be catastrophic if it failed.

Let's play a game.
I give you a pistol with 6 chambers and I tell you that four chambers are empty and there is at least one bullet, possibly two, in the gun. How good do you feel about putting that gun to your head and pulling the trigger?

Not too bad?

Ok, well how about if I take that gun and put it against your child's head (assuming you have a child, just for the purposes of this example) and get ready to pull the trigger? Do you still want me to go ahead and do it? Are you prepared to take that risk? Only it's not just your child, but hundreds of thousands/millions of children who's future's you are gambling with.

Can you see why I feel there just too much at stake to be gambling like that in these circumstances?

The problems that have been caused already are a major global disaster as it is. This is America's Chernobyl. The last thing needed is to risk increasing that disaster to a magnitude that is unimaginable.
