Former U.S. Defense Secretary Ash Carter speaks with The WorldPost’s editor in chief, Nathan Gardels, about the Trump administration’s new China policy, North Korea and the pending U.S. withdrawal from the Intermediate-Range Nuclear Forces Treaty.

Ash Carter discusses public service, opening the military to transgender troops, and North Korea's latest missile launch with actor Jim Parsons on his SiriusXM radio show "Jim Parsons Is Too Stupid For Politics."

From sharply rising tensions with a nuclear North Korea and decertification of the Iran nuclear deal to China’s growing global assertiveness and the State Department pullback from projecting American values, such as democracy and human rights, around the world, the United States faces urgent national security challenges.

In a panel discussion Monday evening at Harvard Kennedy School (HKS) moderated by MSNBC host Rachel Maddow, former members of President Obama’s cabinet described what they see as a fraying of alliances, a loss of credibility with allies and enemies, a stepping back as a leader on human rights and democracy, and a relinquishment of diplomacy as a critical component of national security.

"The liberation of Mosul and the inevitable, approaching liberation of Raqqa in Syria will not be the end of the Islamic State and its evil ideology. But they crush the group’s pretense to having an actual “state” based upon it. As its surviving leaders scurry to the corners of the desert, no longer can they claim to head a winning movement. Their defeat diminishes the inspiration for violent extremists, or simply lost souls on social media, to attack Americans and our friends. This is a necessary step forward in combating terrorism. Americans are safer for it."
