Too often we forget about the victims of geo political wars and sanctions: the people.
Sanctions if used only and selected against evil dictators and their friends seem to be a good balance. However, sanctions against entire countries affect the people more than their leaders and therefore to more harm than good. Syrica, Iran, Venezuale are some examples.
I think we need to openly discuss the agendas behind geo political wars and sanctions to avoid them and move more towards a primarily pacifistic world.
