How does "our responsibility" in Iraq today square up with America's decision to invade and occupy Iraq in 2003?
When it comes to the use of military force, Americans tend to be in two camps: those who want it to defeat our enemies and those who oppose it.
Pope Francis' remarks about armed intervention in Iraq has Catholic commentators trying to explain the nuances of the church's position on humanitarian intervention.
The Vatican's nuncio to Iraq said U.S. military airstrikes "had to be done, otherwise [the Islamic State] could not be stopped."
Even as Francis called for peace in the Middle East, the Vatican tried to come to terms with the idea that U.S. military strikes were necessary and working.
