Following Trump's Afghanistan speech, Secretary of State Rex Tillerson told reporters Tuesday that Pakistan will play an important role in initiating the negotiation process between the U.S. and Afghanistan's Taliban, but noted that the country must first "adopt a different approach" to easing tension in the region.

Tillerson said it's up to the Afghanistan people to decide how to govern themselves, but as long as they don't offer a refuge to terrorists. Message to the Taliban: "You will not win a battlefield victory. We may not win one, but neither will you." Tillerson said North Korea's recent "restraint" in missile testing since the adoption of the U.N. Security Council resolution has "perhaps" created a pathway for potential dialogue between Washington and Pyongyang.
