This book discusses Islam, its relationship with the world, and how Muslims perceive the world and their role within it. Using Islamic scriptures and the works of important Muslim clerics, the author explores the Islamic notion that Muslims represent the best of humanity, and as such, have the duty and the right to propagate their faith throughout the world by any means, including violence.

Islam and the Infidels warns of the dangers Muslim immigration poses to free societies. Using a diplomacy of deceit, Islamists immigrate to Western societies. Having done so, they establish closed ethnic communities that are estranged from their host countries, and are breeding grounds for native-born malcontents who may attack and destroy Western nations from within. The author is especially critical of Western apologists who not only pretend that Islam is not inherently aggressive and dangerous, but also denigrate those who point out the threat to liberal values posed by fundamentalist Islamic ideology.

Bukay argues that to meet the Islamic threat, the West must understand Islam's true nature, and the best way of doing so is by analysing its scriptures and history. Bukay argues that Western societies should embrace the Judeo-Christian tradition, which is the root of their cultural heritage. In light of the mounting Muslim threat to liberalism in Western societies, citizens should resist oppressive Islamic practices and doctrines rather than accept them.
