New legislation should treat a resident alien’s or prospective visitor’s known or suspected adherence to an Islamic world outlook as excludable – on political, rather than “religious” grounds. The broad model is provided by the 1952 Immigration and Nationality Act (INA, the McCarran-Walter Act). It is possible that the “affiliation” in this clause will affect a number of people who do not actively identify with the goals and methods of the Jihadist core. That may be unfortunate but it is inevitable. Personal assurances by individuals thus affected cannot be taken at face value: Islam not only allows, but mandates lying to “infidels” in order to gain political or any other advantage (i.e. Taqiyya, the concealment of one’s Islamic beliefs to non-Muslims). The problem is well known to INS officials: attitudes of Muslims who apply for U.S. visas or asylum often change once their status in America is secure. When applying they complain about the lack of freedom in their native country. When they gain permanent residence, let alone citizenship, they often turn against their host nation and praise the virtues of an Islamic state. In addition, even “lapsed” Muslims are at permanent risk of going back to their roots, as many Western-born youths are doing.
