Interesting to see a rare grouping of the BRIC's in attacking the IMF and wanting to seize the crown. When one considers the history of the IMF, with its poor policies in the 80's that wrecked many a country and its perception (see picture) of being a Western tool for control of developing counties, this should be no surprise. The IMF is a tool of western imperialism in the minds of many of those on the receiving end of its policies.
One problem with this is that overall, the view expressed above is wrong. The IMF exists to save countries and often the worst that can be said about it is that in acting so late in the day, the problems have already overtaken he ability of a Country to cope - leading to default and mass austerity for the population. The IMF is an ambulance; the patient is already seriously wounded on arrival and emergency treatment is hazardous without guarantees pf success.
Now, though is a new century and with the Western powers themselves excruciatingly weak, it is a good time to strike. However, I doubt very much even if a non-European head was appointed that it would make much difference. The glamour of being an international civil servant and the mindset that goes with it will soon affect any incumbent (after all, in order to apply you need to be from this cadre already) - and it will be back to business as usual.
The worry must be for the Europeans who are trying to get the IMF to hep the Euro without agreeing fair terms - however, this is going to fail anyway as the European debt crisis spirals over the next few months and years.
