A war is won when a nation state is eliminated or surrenders. You can only defeat terrorism by eliminating all the terrorists which is impossible as long as an ideology persists. Not having a nation state status means things like the Geneva convention don’t even apply to you and you have no head of state that can be taken down or map that can be redrawn, there is no feasible endpoint to your wrath and you are only as peaceful as your least peaceful member. This is a cancerous state of affairs. Terrorism and war are fine lines and I’m not arguing sides here as far as who’s actions, present day or historical are More or less just. But yeah, I’ll always come down harsh on terrorist organizations, they take wars that could have discreet endpoints and allow them to last forever.
