WASHINGTON (AP) — Democratic presidential candidate Martin O'Malley said Friday the rise of the Islamic State group was an unintended consequence of a "mindless rush to war" in Iraq and the U.S. must avoid "mission creep" there now. "No threat probably better illustrates the unintended consequences of a mindless rush to war — and a lack of understanding — than the emergence of ISIS," O'Malley said in his first foreign policy address as a presidential candidate, using an acronym for the Islamic State group. O'Malley said American foreign and national security policies are directly connected to economic stability around the globe and a rising global middle class. Ahead of next week's deadline on Iran talks, O'Malley said a nuclear-armed Iran is among the most immediate threats faced by the U.S.
