ground zero

"The point directly above, below, or at which a nuclear explosion occurs" (Merriam-Webster). Recently thanks to a load of rhetoric from our idiot newscasters, the meaning has been horribly trivialized. Hiroshima (80,000 deaths from the explosion + additional 60,000 deaths from radiation poisoning) is a "ground zero". Nagasaki (120,000 deaths total) is a "ground zero". The World Trade Center (2749 deaths) is NOT a "ground zero". So stop calling it that.
