From C&L:
...[Shepard] Smith originally brought on Christopher Brownfield to discuss the potential for using a nuclear bomb to stop the leak
Brownfield: If we demolish the well using explosives, the investment's gone. They lose hundreds of millions of dollars, from the drilling of the well, plus no lawmaker in his right mind would allow BP to drill again in that same spot. So basically, it's an all-or-nothing thing with BP: They either keep the well alive, or they lose their whole investment and all the oil that they could potentially get from that well.
Brownfield: Yes, I think -- stopping the spill immediately. And the reason why we haven't seen that option is because, frankly, BP is still at the helm. I think President Obama needs to take charge of this, bring all the assets of our military to bear, bring the U.S. Army Corps of engineers, bring the U.S. Navy, and bring in all the private-sector organizations that have the equipment for deep-sea operations to make this happen. Let's explode this, collapse the well, and put an end to it...
