US can't kill its way out of this mess: Mitt Romney on terror

Boca Raton, Florida: White House challenger Mitt Romney warned on Monday that US President Barack Obama's policy of deploying deadly force against Islamist militants would not be enough to end the extremist threat.

"I congratulate him on taking out Osama Bin Laden and going after the leadership in Al Qaeda, but we can't kill our way out of this mess," Mr Romney said, as the pair's last debate of the presidential campaign began.
