Please tell me about the strengths of Germany, France, and Brazil.

‌Since the 80s, Germany, France, and Brazil have mostly been in Tier 1, followed by Argentina, Italy, Spain, etc., in Tier 2..
While Argentina, Italy, and Spain have consistently been contenders or title favorites in the World Cup, I understand that Germany, France, and Brazil have had many tournaments where they were several times more dominant than the others since the 80s. What exactly are the strengths of Germany, France, and Brazil?
Although Argentina and Spain are performing well now, if you look at the total record from the 80s to the present, Germany, France, and Brazil are the top Tier 1, followed by Argentina, Italy, Spain, etc.
Below them, England, Portugal, the Netherlands, Croatia, Belgium, Switzerland, etc., are likely positioned..
Below those, there are non-European and non-South American powerhouses like Mexico, the USA, Japan, and South Korea, but is Mexico the strongest among them?
