The Summit was more than empty words – it made clear that a solution-driven approach is the only way to fight hate. That’s why the working group activities, which are results driven are going to be critical in defeating violent extremism. The Summit brought together the best minds in government, private sector, academia, and civil society. Being surrounded by these experts sparked new ideas – some of which I’ve already implemented or have written about.
