After conducting a six-year study, David Vine, professor of anthropology at American University, has published a new book titled Base Nation: How U.S. Military Bases Abroad Harm America and the World in which he argues that military bases abroad are undermining U.S. national security and American soft power abroad.

"I can truly feel the world's growing interest in Korea whenever I go on a business trip, Yu said. "And I believe that now is the time to put more effort into public diplomacy. The result will be greater than expected."

But the new relationship will give American diplomats greater leeway to reach out to dissidents. Instead of asking permission to travel around the island, diplomats simply have to notify the government of their travel plans. Not ideal, but then Cuba is not a free country. That’s the whole point of the new policy, to achieve by engagement — soft power, if you will — what hard power could not achieve during the Cold War and beyond.

Soft-power sound war escalates as Seoul and Pyongyang turn up the volume on propaganda transmitted over border.[...] South and North Korea have begun a high-volume propaganda war, blasting radio broadcasts across the demilitarised zone after a landmine explosion exacerbated tensions along the border between the two countries.

ASEAN members are focusing on important emerging issues in the region and have opted to approach them using soft diplomacy, with soccer as one of their tools. 

So in this background, no instrumentality like diplomacy, intelligence, perception management, media, use of soft power, influencing minds of the people, that have become new instruments of the statecraft.
