Post-liberal peace theories advocate hybrid forms of security governance, coherence, cooperation. NGOs and military forces represent (aside local communities and political leadership) main actors in complex emergencies. Despite the roles of these inherently difference actors (difference purposes, different aims and organisational cultures), their functions are complementary. Nonetheless, many NGOs are reluctant to cooperate with armed forces/military (which have more or less a political agenda and most of the times, are active parties in a conflict) on grounds of impartiality, neutrality and security. What theory, approach or understanding could help overcome this deadlock? I would be very thankful for your inputs.
