Wild Fire: Number 4 in series by Nelson DeMille
A group of Vietnam Vets who still keep in touch: the Custer Hill Club. Prepared to attack foreign countries if America is attacked, their current rule is that if an Islamic country attacks America, all Islamic countries will have to be nuked.
But the Custer Hill Club are getting more ambitious and more aggressive. Driven by an obsessional desire to destroy Mecca, the Aswan Dam and other spearheads of Islam, the men soon decide to nuke an American city themselves. So long as the world thinks the attack is down to Islamic terrorists, the men are free to play with fire as they please . . .
America will rule the world!
