And these same Islamic terrorists may also be using Mexico as the conduit to bring nuclear devices into the U.S. for a WMD attack. These are among the chilling disclosure from Paul L. Williams, author of the just-released book"The Day of Islam: The Annihilation of America and the Western World."

According to Williams, al-Qaida has already hatched plans to smuggle nuclear materials across the Mexican border and use them for a mammoth simultaneous attack on several large U.S. cities.

Al-Qaida and other terrorist groups began infiltrating Mexico in the days after 9/11. By 2003, Canadian intelligence officials and Interpol told Mexican President Vincente Fox that al-Qaida had established several cells in Mexico to prepare for the next terrorist attacks, Williams tells readers.

Meanwhile hundreds of Tzozil Indians in southern Mexico converted to Islam and reportedly became involved in subversive activities. By 2004, al-Qaida cells were in place in northern Mexico and a large cell of Hezbollah was in Tijuana, on the U.S. border of California. The Muslim radicals enlisted the aid of Latino gangs, including Mara Salvatrucha, to help them slip across the border.

According to Williams, the going rate for such service was from $30,000 to $50,000, but it included a bogus matricular consular, an official ID card issued by the Mexican government that enables Mexican nationals in the U.S. to obtain drivers licenses and open bank accounts.

Steve McCraw, assistant director of the FBI's Office of Intelligence, told the House Judiciary Committee in June 2003:
"The ability of foreign nationals to use the matricular consular provides an opportunity for terrorists to move freely within the United States without triggering name-based watch lists that are disseminated to local police officials."

Mexico has also become a conduit for aliens from terror-sponsoring states, known as "special-interest aliens," or SIAs. By 2006, a popular entry route from Mexico into Arizona was littered with "discarded Muslim prayer rugs, pages from the Quran, instructions in Arabic on how to cross the Rio Grande, and beverage boxes with Farsi and Arabic letters," writes Williams, a seasoned investigative reporter and former FBI consultant.

Due to a lack of detention facilities, those SIAs that are apprehended — who have numbered in the thousands in recent years — are released from custody after receiving hearing dates from immigration judges. Fewer than 5 percent actually show up for their hearing. The rest simply vanish.

Texas Rep. Solomon Ortiz, a Democrat on the House Armed Services Committee's Subcommittee on Readiness, said the release of Middle Easterners with possible links to al-Qaida is "very, very scary and members of Congress know about this."

In April 2004, the FBI arrested al-Qaida operative Mohammed Junaid Babar, after he returned to New York City from a terrorist summit meeting in Pakistan. He told interrogators that al-Qaida was preparing a nuclear attack on American cities. He also said the terrorists were relying on Latino gangs, most notably Mara Salvatrucha, to transport the operatives, along with nuclear supplies, across the U.S.-Mexican border.

Another captured terrorist later confirmed Babar's account. And both men said the plot was being directed by Adnan el-Shukrijumah, the man profiled in a NewsMax story last week — whom Williams calls "the most dangerous person in the Western world."
