A recent article states that IS claims it will have a nuclear weapon, and have it smuggled into the US, by this time next year.

The article is certainly not great, as it was written by a journalist in captivity by the IS, so it's more propaganda than reality. However, if a terrorist organization actually detonated (or even just smuggled in but failed to detonate) a nuclear weapon within the US borders, what do you think our reaction would be? Should be?
