DT, i tend to agree with the points you raised, Greece is teetering on the brink, China's economy is surely slowing, America is about to re elect Obama. I would be very very surprised if Mitt Romney were to win, that would lead to a more unsettled USA. Perhaps with Obama four more years will see a better turn around for the US economy..
However i would like to see a total withdrawal of all troops from Afghanistan, there never was a valid reason to be there, and it's an unwinnable situation.
Britain will stagger on a bit longer, but can see more protests on the streets and more job losses.
If the EU doesn't start getting it's act together it will also see the larger nations going under, Spain already in dire trouble, and Italy to follow.
If the idea that has been mooted for a EU financial union then all hell will break loose, led by the money men in London, they will not wear it, and indeed why should we.
