If a leader of a country said of your country that it needed to be wiped off the map, what would you say of its intentions, hostile perhaps? If you choose to find wiggle room between saying your country needed to be wiped off the map and saying it would attack, I at least hope you see how one might interpert it as a threat of violence.
