Military interventions spread them, democratization brought them to power and immigration transplanted them from war zones into our countries. Their numbers have more than doubled in a decade. If the Left gets to set foreign policy again, in another generation there will be millions.

If we want to avert that outcome, our interventions, regime change and immigration policies must all objectively meet the test of making societies, including our own, less Islamist, not more so.... Foreign aid should be barred by law from going to any country or militia whose goal is to establish Islamic theocracy by force. Any intervention must be objectively shown to make a society less bound to Islamic law. And immigration policy must be aimed at reducing the percentage of Islamists in the United States.
