What's in a word

Very good little essay from The Economist (here) about the power of words and why it is important to use some of them carefully.

A quick excerpt:
THE “global war on terror” is what America calls its response to the September 11th attacks. Never mind the cliché, or the fact that “terrorism” is a tactic and “terror” a state of mind; George Bush's crisp slogan helped to rally a traumatized American public.
