IMO, UAE is not going to "invade" anybody.
As for whether the US will "invade" SA, what is GWB going to do to sell that idea...hint, suggest, repeat in every speech that SA has those pesky WMD, or perhaps he'll get his team to appear on pol talk shows to say SA has those pesky WMD - does anyone REALLY expect the country will buy THAT tale again?
GWB became a lame duck president early last year - which is very early for a 2nd term presidency - when he tried in vein to push for SS "reform" with his private investment plan. Not even his own party supported him, so he quietly dropped what he had previously called "necessary reform to save SS".
