15 of the Strangest Things That Have Caused International Incidents
When we think about international incidents, Hollywood movies and conspiratorial superstition drives us to think about spies, wars, or everything in between. And yet, these conflicts involve people like any of us, meaning that they can spark from seemingly innocuous things.
