WASHINGTON (AP) — If he's elected president next November, Ted Cruz vows a dramatic shift in how America engages with the world.

Cruz promises to destroy the Islamic State, beat back aggression from Russia, China and Iran, and ensure terrorists don't infiltrate the U.S. homeland.

Yet he also places notable limits on his approach to national security. In an interview with The Associated Press, he outlines a prospective foreign policy that is both broadly ambitious and cautious at times in the specifics.

In an election increasingly focused on national security in the wake of the Paris attacks, Cruz says he has one goal above all others once in the Oval Office.

He says, "the pre-eminent job of the commander-in-chief is to keep this country safe. It is the first responsibility."
