It means that you have been wholesale influenced rather than informed about the conflict that politicians are peddling to you, as you don't have a grasp on the most basic facts of the matter. We're talking of civilian support for acts of war here.

Specially since an actual war with the people of that polity is an obvious outcome.

If one lacks the knowledge to even identify another nation on the global map, you have to wonder if this person actually has strong, sound judgement (when they speak in favor of dropping bombs) or if they’re easily malleable partisans.
