This Balearic-sounding track is based on a long distance relationship that Future Islands frontman Samuel Herring had in 2016. "Falling in love with someone who lives thousands of miles away is the only way I've known how to fall in love for the last few years of my life, he told Q Magazine. "I've been here before. Then you ask those questions: 'Why do you put yourself in that position? Why can't you fall in love with someone who lives up the street?'"
Dido helped shut down a Neo-Nazi Web site after learning it was using "White Flag" to promote its hateful messages. Owners of the site had misinterpreted the track as racist and thought they represented their white supremacy views.
