US President Barack Obama has, for the first time, admitted he would deploy US ground troops to Syria and Iraq to fight Islamic State - that is, if the extremist group obtained a nuclear weapon.
“If we discovered that [Islamic State] had gotten possession of a nuclear weapon, and we had to run an operation to get it out of their hands, then, yes,” Obama told reporters at a news conference in Brisbane, Australia, on Sunday. “I would order it."
Since Operation Inherent Resolve - or US-led airstrikes against Islamic State (also known as ISIS or ISIL) - began in August, President Obama has maintained that he would not send a large fighting force to Syria and Iraq to confront the jihadist network, which has come to control large areas of the two adjacent Middle Eastern nations.
