Both have a diverse population. Brazil is a mix of all sorts of people and Israel is a mix of Arabs, Ashkenazi, Mizrahim, sephardim, ethiopians, even mountain jews, bukharian jews etc.

Both are beach nations with an awesome party culture + modern cities like Tel Aviv or Fortaleza that make you want to stay there forever and just live at that pace of life

But they also have their "older" more conservative areas like Jerusalem or Ouro Preto

Both have to balance international relations in a very complex and difficult way

Both outpace their regional "rivals" and friends in amazingly awesome ways

Both have a culture of beach babes, volleyball, and chillaxing while still being die hard patriots and lovers of the flag
