It's often difficult to talk about difficult and stressful situations, loss and suffering, and about things seen but never forgotten, I'm not surprised she doesn't tell you everything. Sad, but a reality of a situation like hers.
I understand that people want to have hope, I think it's convenient and comforting for people to say things like, humanity is moving towards peace, but the fact of it is that humans are constantly in conflict, one after the other with small gaps of peace planning the next conflict in between. Emotions like greed, selfishness, ego and hubris are for too strong in humans and most act commensurate to those emotions. It's easy to blame the agendas of politicians, corporations and hunger for money as people do, but it's all humans...all to blame.
