As President Obama declared in his Nobel Prize acceptance speech "We must begin by acknowledging the hard truth that we will not eradicate violent conflict in our lifetimes," new details were emerging from Pakistan, where  five American Muslims have been detained on suspicions of possible involvement in terrorism. Law enforcement in that country said the United States nationals, who disappeared from Washington D.C. last month, were suspected of planning attacks against "American interests" in Pakistan.

Aleem Maqbool, Islamabad correspondent for the BBC, joins the conversation about these five young men, ages 19-25, whose families recently asked for help in finding them. One possible piece of evidence in the case is a video the men left behind, featuring scenes of armed conflict and a message that young Muslims had to do more.
