zimbabwe.....the drums are beating.

Any views on how Mugabe's threat to nationalise fuel might effect suppies to the mines and, dare I even canvas the possibility of an attempt to nationalise mines.
ZIM has held on to most of it's recent rise, up from around $1:28 or so. There is a relatively high risk factor already built into this price, but I wonder does anyone here think that nationalising could become a reality.
Mugabe has the track record, but surely even he knows that Zimbabwe needs foreign investment/currency etc..
I guess the question I'm asking is, would he be prepared to put all that at risk?
Appreciate any thoughts on the matter.
Cheers,
Carl.
