In that case it's Brazil. Although it's fairly interesting that at the lower weights the Brazilians seem to get weaker (other than Aldo obviously).
Brazil has had multiple champions in mma in general. Outside ufc look at strikeforce and other mma organization. Most of the champs are from brazil. Strikeforce champs Ronaldo "jacare" Souza Rafael Cavalcante UFC Mw champs Anderson silva LHW- shogun rua Fw- jose aldo former champs big nog belfort wanderlei silva Machida Bustamante Royce 1st ufc champ
America Brazil Heavyweight - Cain Velasquez vs Junior Dos Santos Light Heavyweight - Jon Jones vs Shogun Rua Middleweight - Chael Sonnen vs Anderson Silva II Welterweight - Jon Fitch vs Thiago Alves III Lightweight - Frankie Edgar vs Gesias Cavalcante Featherweight - Chad Mendes vs Jose Aldo Bantamweight - Urijah Faber vs Wagney Fabiano I think Brazil wins 4-3 behind JDS, Shogun, Anderson, and Aldo.
