What are the BRICS countries? Go to: http://en.wikipedia.org/wiki/BRICS
This group may owe quite a bit historically to the USA but now it is an attempt, properly from my viewpoint, to create a countervailing power group to the USA. My justification would be the erratic nature of short and long term USA policy formulation and strategy. I would also argue that only two are democracy oriented, but barely.
All except Russia have huge populations. And they are rapidly growing. Russian population is in rapid decline. Both for public health, environmental and lifestyle choices. Warnings to NOT adopt Russian children due to fetal alcohol poisoning are still in place. FEW white Americans adopt children from the BRICS, and with the Chinese precluding adoption of female babies this block is pretty much in place with only Russia as an exception. Many many Americans trace their heritage to Russia and China and India but few do to S. Africa or Brazil. And black Americans seldom adopt formerly domestically or internationally.
The advantage of INDIA of course is that English is the language of the dominant class and to enter you must speak english. South Africa of course also has a political and economic class that is English speaking. Brazil is Portugese in origins and language. Note that South Africa is not the largest AFRICAN nation-state–that is Nigeria which recently became majority Muslim.
It will be interesting to watch the BRICS develop various economic and political links. Personally I think Russia east of the URALS this time next century may well not be Russian. German and Russian economic links forge tighter and tighter and probably would be even closer without the presence of the obsolete NATO. The Libyan intervention will prove how obsolete NATO is as a military alliance. The Han Chinese cross the Russian border into Siberia in large numbers each month.
So this will be interesting to watch play out.
