The failure of Islamic states to incorporate the Enlightenment's advances in thought has caused their stagnation, if not decline, over the last several centuries. In contrast, the incorporation of Enlightenment and democratic principles into Western governance has resulted in history's most rapid improvement in the human condition. Only those Muslim countries that have embraced, in some fashion, Western principles of democracy, free markets, property rights, tolerance, and the rule of law have prospered. Most Arab states refuse. Bernard Lewis, perhaps the doyen of Middle East studies in the Western world, explained, "By all indicators from the United Nations, the World Bank, and other authorities, Muslim countries—in matters such as job creation, education, technology, and productivity—lag ever further behind the West. Even worse, the Arab nations also lag behind the more recent recruits to Western style modernity, such as Korea, Taiwan, and Singapore." All majority Muslim countries except Qatar, Bahrain, Kuwait, Oman, and Turkey, which have recently adopted significant free market and democratic reforms, rank in the bottom half of world productivity; of the rest, only Morocco, Indonesia, Saudi Arabia, and Bangladesh reach the third quartile. According to the World Bank, the average per capita income of all majority Muslim countries collectively is less than half of the average for the globe. Only Kuwait approaches the global average life expectancy; all other Muslim majority states lag in the bottom half of the world in this important measure of health.

Jihadis thrive in such stagnated conditions. This leads to negative annuity: Jihadism both grows amid stagnation and fuels stagnation. It accelerated coincident with the European Enlightenment and the relative decline of the Muslim Middle East. At its core, jihadism is a violent rejection of many of the fundamental principles of the European Enlightenment. Democracy, free markets, tolerance and freedom of religion, secular government, and separation between the religious, the political, and the individual spark religious fury. It is no coincidence, then, that jihadis, under the banner of cleansing their religion of evil Western influence, have focused their attentions on the United States, the clearest manifestation of the European Enlightenment today. They will continue to threaten Western civilization until they are checked.
