The problem is what if it doesn't work? What if it makes it worse? The Russians only had a 4 out of 5 success rate. They were using it on land only, not a mile deep in the ocean. But I am no expert. This option should be condidered by experts.
Also, remember that our Usurper in Chief is anti-nuke.
Not sure if I trust they're info.
The kicker is getting the nuke down hole past the BOP, If they can do that then they can run a packer and if they can do that then they can plug this thing and not need to try anything as dangerous as firing off a nuke downhole.
The main problem with using a nuke to close the deepwater well is that you are using a nuke to cause a landslide. Causing a landslide underwater could lead to a tsunami at the surface if they move more land then they intended. If they do use a nuke, the entire coast of the GOM needs to be evacuated. With Obama in power, they probably wont let us know when they use the nuke, and we wont be able to evacuate.
