Changes is needed when you're with the western bloc and your country economy is getting worse without any aid from the US. US has been a country that is only concerned about its citizens and they don't give a fuck about the economical growth of those small countries in UN. US only go to assit countries that they will benefit huge profits from.

If the US wouldn't benefit anything from you, they don't have any business to do with your country. BRICS is the only alternative to those countries who wants to be free from the UN. I believe that many more countries will join BRICS in future and that will weaken the US dollar and power in the world.
