...If you know the carrier — Saudi Arabia — and the disease — jihadist Islam spread with Saudi funding through mosques staffed with Wahhabist imams in America and Europe — why blithely allow it to continue?

Yet continue it surely does. Like clockwork, every month, Saudi dollars flow in to build and staff more mosques, from one end of Europe to the other and in every American city. Because Muslim communities in America do not advertise having them, it is difficult to get precise statistics, but Saudi-trained imams originally from Egypt or Pakistan are streaming into America using visas that identify them as "religious guides."

Recently, I stumbled up to a minivan filled with six such new arrivals in front of the Beacon Theater on 75th Street — all of whom were staring at women in short skirts like children let loose in a candy shop. I spoke to them and discovered that they had just arrived from Al Azhar University School of Theology in Cairo, for years now largely a Saudi-controlled Wahhabist seminary, and they were headed to multiple mosques after being sponsored by several Muslim communities in New Jersey and New York.

They spoke no English but, as one told me, there was no need for that. "We preach in Arabic," to Arabs, he said.

It is not insignificant that President Sarkozy of France, whose 60 million citizens include some 5 million Muslims, has decreed that the only imams now permitted to staff French mosques must have been trained in France and be fluent in French.

Over the past year, France has quietly suspended scores of imams who do not meet these criteria. Many are being sent back home to Morocco or Egypt.

America should get a National Intelligence Estimate that tells us how many of the imams coming into this country have an "elemental knowledge" of America's Constitution, its Bill of Rights, and its essential values, such as freedom of speech and the rights of women...
