"Iran issues a sharp warning to the US" stop threatening us about those damn nukes or "we'll cut you!" Really? It sounds like a school yard threat, "stop picking on us big US bully, that's a sharp warning!" Of, course, being the big US bully in the school yard in my day, my response would be: See my pet birdie in the sky dropping a special package just for you? . . . Ka Boom! Now that's a warning . . . oh wait, skipped warning, that's a bullseye!
