US Senator Tammy Duckworth (D-IL), a combat pilot who lost both her legs in Iraq, joins GZERO World to reflect on the 20th anniversary of the US-led invasion. In her conversation with Ian Bremmer, Duckworth says that the first thing people need to understand is that the "cost of war" goes on far longer than the period of actual conflict. She emphasizes the importance of “fulfilling promises made to veterans,” and says it's "non-negotiable."

While acknowledging the progress made in Iraq after Saddam Hussein was removed from power, Duckworth believes that the country "is somewhat unfinished business," and worries about high unemployment rates for young people, concerns about Iranian influence, and negative oversight of the Kurdistan region. She hopes Iraq can become “a friend and ally to the United States.”
