Kara, one more thought
Toward the end of WWll, the suggestion was made to drop a nuclear bomb close to, but not directly on the Japanese Islands. Close enough to, well, GET THEIR ATTENTION. Looking back on the devastation that was caused, I believe it would have achieved at least that.
But in a wartime state of mind, and with the warning of 100,s of thousands of American casualties to actually conquer the islands, fear won out.
