I was posting to another thread awhile ago, and this came to mind. I haven't heard the Term used much lately, so I thought I'd do a little googling.
The coalition was formed to confront the alleged threat posed to the World's stability by Iraq, but from what I've read it seems to have lost it's
momentum.

Of the other five, all the most prominent leaders of the “coalition of the willing”, only Anders Fogh Rasmussen, the Danish Prime Minister, is
still standing. The others — Mr Blair, José María Aznar, of Spain, Silvio Berlusconi of Italy and Junichiro Koizumi, of Japan — are all gone,
variously hounded out of office by angry voters, resigning with a tainted legacy, plotting political comebacks or keeping out of the limelight, burnt
out by the intensity of the Iraq misadventure.
