The Last Jihad by Joel C. Rosenberg (2002, Hardcover)

Saddam Hussein dispatches his top assassins to the United States.
Iraqi hitmen spread carnage throughout London, Paris, and Riyadh.
And the Butcher of Baghdad is just getting started.

Only a rock-solid Arab-Israeli coalition against Iraq can keep the U.S.-and other Western nations-from certain devastation. And only Bennett and his beautiful partner, Erin McCoy, can make that happen. Their secret project, a billion-dollar oil deal off the coast of Gaza, could be the basis for an historic peace treaty and enormous wealth for every Israeli and Palestinian.
But just before the treaty can be signed, Israeli commandos foil an Iraqi Scud missile launch, recovering a nuclear warhead and evidence that Iraq's next attacks will level Washington, New York, and Tel Aviv.

Now the Israeli prime minister gives the American president an ultimatum: Melt down Baghdad within one hour--or Israel will do it herself.

From Jerusalem, Bennett and McCoy must summon all their stealth and savvy to save themselves-and the world-from absolute destruction.
