Why are children starving to death in Zimbabwe?

They are in the position because of their corrupt goverment that work along side mafias and gangstas to keep a hierarchy... them at the top, the general public at the bottom. Suppressing them and keeping them suppressed allows the regime to carry on.. charity money raised by the likes of Live Aid etc. is disappearing into the governments and mafias pockets, whilst they starve to death. Other governments i.e. the united nations probably won't tackle the corrupt government simply because, it is not their problem.. and they can see no benefit for themselves... unlike Iraq who have large quantities of oil supplies.
