i don't think so. a self-inflicted wound on that scale would be too expensive, too big of a loss. it would also likely cause a massive civilian revolt as they lose all trust in their government entirely. it would also cause all of the lovely immigrants our government is replacing us with to flee like rats from a burning ship.  what i'm not entirely closed to is the possibility that they are flying nuke-sniffing drones, and they will "find" a nuke, then point at the country of their own choice to start ww3 with.
