The Islamic State terrorists are an existential threat to the world. They have pledged attacks on the United States, proclaiming that their flag will fly over the White House. They show no signs of stopping either. Despite U.S. airstrikes, which are very likely to increase their popularity and help with recruiting efforts, the Islamic State is redoubling their attacks and intends to spread across the entire Middle East. If they are somehow defeated in Iraq and Syria, the survivors are likely to disperse and conduct terror attacks wherever they can, including in the United States. Presently, Christians and others who refuse to accept their rule, are being subjected to all forms of torture and killing. Beheading is a favorite, although simple shooting is common. In another report, about 500 Yadizi people were buried alive. The remainder who have not fled the Islamic State are being ordered to convert or die within 24 hours.
