Recently, FBI Director Robert Mueller, in an interview with NewsMax, confirmed Williams' main claim. Mueller said al-Qaida's paramount goal is clear: to detonate a nuclear device that would kill hundreds of thousands of Americans.
Mueller told NewsMax that at times, the threat feels so real he lies awake at night thinking about the prospect.
Williams maintains that al-Qaida is not content on blowing up one nuclear device or even simply a "dirty" nuke — but wants to explode real nuclear devices in seven U.S. cities simultaneously.
Williams says these cities are New York, Washington, D.C., Las Vegas, Miami, Boston, Houston, and Los Angeles.
Mueller seems to confirm this claim of multiple attacks, saying both New York and Washington would be likely targets. Already Williams says the U.S. government has Washington webbed by "choke" points to detect nuclear material.
For many Americans the threat of al-Qaida's nuclear ambitions begins in the time after the horrific 9/11 attacks.
But as Williams shows so clearly, al-Qaida has been devising its nuclear plan since the early 1990s — and the U.S. government and other intelligence services have been well aware of al-Qaida's plan.
