Funny think about that. Only a couple of days ago I was watching TV and a Brazilian referred to being American, in Portuguese of course.
The constitution of 1891, establishing the United States of Brazil (Estados Unidos do Brasil), granted extensive autonomy to the provinces, now called States.They changed to Federative Republic of Brazil (República Federativa do Brasil) after their military coup d'état in 1964.
Brazil appears to be proud that considering the continental landmass only, they are the largest country in the Western Hemisphere.
The US is larger in area than Brazil
