that current immigration policy would lead to ethnic and religious division, nation states will lose their monopoly of force, Islamic law (sharia) will be introduced at the level of neighborhoods and cities, and exploitation of women and children will become "commonplace". To avoid this situation, she proposes three general principles for a new policy: Admission of immigrants on the basis of their contribution to the economy. The current system "is designed to attract the highest number of people with truly heartbreaking stories". Diplomatic, economic and military interventions in countries that cause large migrant flows. Introduction of assimilation programs that acknowledge that "the basic tenets of Islam are a major obstacle to integration". Regarding unemployment, social marginalization and poverty among certain immigrant communities, Hirsi Ali places the burden of responsibility squarely on Islam and migrant culture. In 2010, she opposed the idea of preventing immigrants from traditional Muslim societies from immigrating, claiming that allowing them to immigrate made the U.S. a "highly moral country". The subject is also discussed in her 2017 Hoover Institution Press publication "The Challenge of Dawa, Political Islam as Ideology and Movement and How to Counter It". In 2017, Hirsi Ali identified what she regarded as four categories of Muslim immigrants and asylum seekers in the West she has encountered in her personal and professional life: Adapters, who over time embrace core values of Western democracies, adapt to public life and use freedoms found in the West to educate and economically better themselves. Menaces, mostly poorly assimilated young men who routinely commit crimes and acts of violence. Coasters, men and women with little formal education who live off welfare and use lax immigration rules to invite extended family to do the same. Fanatics, who abuse freedoms given to them in Western nations that gave them sanctuary to impose an uncompromising practice of Islam. However, she also maintained that each category is not rigid and menaces can become fanatics by becoming exposed to Islamism in prison while the children of immigrant adapters can turn into fanatics through rejecting liberalism and embracing stricter and fundamentalist branches of Islam. She has also written in support of refusing residency and citizenship to those who cannot become adapters. Assimilation "When I speak of assimilation", Ali clarifies, "I mean assimilation into civilization. Aboriginals, Afghanis, Somalis, Arabs, Native Americans—all these non-Western groups have to make that transition to modernity". Sadiya Abubakar Isa criticized these
