NATO's 20th century strategy was building walls. That led to a lot of death. Instead, we need to build bridges with what Stavridis, the NATO supreme commander, calls open source security.
He identifies threats to the global commons: piracy in the seas, cyber crimes (which are a $2trillion per year industry), drug, weapon, and human trafficking. While there is a need for strong military, we won't deliver security solely from military means. We need international "public private partnerships for strategic communication on the internet."
For instance, NATO helps private entities and development agencies teach literacy. They have -taught 200k people in Afghanistan how to read. They also work with humanitarian organizations to provide medical care to hundreds of thousands of people. They also work in disaster relief and building diplomacy through sports.
