even Brazil has a space program. but the chances at success are not very high.
Russia has more hand-me-down image, gadgets and old capital than Brazil, but quite appearently less ability or determination to root out the fundamental reason for its current weakness.
The chances of Brazil's success in the medium to long term, say 25-50 years, is IMHO underestimated. It probably won't become one of two or three superpowers, but its size and population means it would probably displace United States to become the regional hegemon of South America, and by that put itself above the likes of France, UK, and Japan as a global power, and become a important, if not dominant, player in the balance of power in the Pacific.
Before that will happen there will probably be a period when the US would attempt to cultivate argentina and Chile to balance the power of emergent Brazil in order to maintain America's dominant role in South America, much as US would attempt to cultivate India and Japan to balance the power of emergent China to maintain America's dominant role in Asia.
