Track 1 or Track 2? Yesterday, our Executive Director Ambassador @ThGreminger spoke to 200+ International Relations students at @unige_en about how informal diplomacy builds trust & paves the way for official agreements. An inspiring talk & many great questions from the students.

#GPF26 may be over, but choosing peace is not a one-week commitment. Choose dialogue over confrontation. Cooperation over fragmentation. Prevention over crisis response. That work continues —in Geneva and far beyond. #GenevaPeaceForum #ChoosePeace @ThGreminger
