Despite screwing up Iraq, I think its very much odds-on that they're going to invade or attack somewhere else during the next Bush term, probably Iran. The spying, air incursions, threats, and neo-con position papers seem to me to strongly suggest that is their inclination.
I agree with general line of the argument here that war is extremely counter-productive. But Bush & co are so detached from reality that I feel they don't listen to reason. (Marek for Pres I say!

But I've got a bad thought for you:
If there is a UK general election in May, and Tony Bliar (sic) gets back in, perhaps with a reduced, but still unassailable majority, what's to stop him dragging us into the next neocon military mess?
Eh?
I know pundits have said, Britain won't do it and TB would have to resign, but he ignored the anti-war movement last time, the Labour party and MPs have not shown any backbone, and despite
ImpeachBlair.org if he has a large enough majority he can do anything he likes. Another war would make a round half dozen during his premiership, so why not?

I hope nobody's going to tell me just because they've made a few denials
pre election that there won't suddenly be some WMDs to find somewhere which changes the situation....
