In Brazil these days, armor is the new normal. From bullet-proof luxury rides to the caveirão, a police assault wagon built like a tank, Brazilians have fortified themselves against the hazards of modern living. In Rio, one evangelical Christian church in a crime-ridden favela is raising a steel-plated, 30-meter containing wall to keep the flock from harm's way when the shooting starts. So fashionable is the concept these days that Brazilians have even come to believe that their charmed economy is innured to world economic downturn.

No doubt there is some ground for optimism. Inflation is under control. Hard currency reserves are topping $160 billion, a continental record. Foreign debt is history. And while the largest economy on earth skates on the edge of recession, Brazilian officials confidently project growth of 5 percent or more this year, or, if the international markets tank, "maybe a little less," shrugs Finance Minister Guido Mantega. Give us your best shot, the bulls in Brazil seem to be saying, for Latin America's drowsy  giant has not only stirred but "decoupled" - or broken free - from the vagaries of the globe's overlord economy.
