Speaking in Estonia today, President Obama issued a warning to the extremist group that took responsibility for beheading two American journalists: "We will not be intimidated," Obama said, according to Time. "Those who make the mistake of harming Americans will learn that we will not forget, and that our reach is long, and that justice will be served."
