I looked at the WC statistics over the years and based on that I have to agree that Germany, Brazil and Italy are far ahead of anyone else.
Semi-final appearances:
Germany 13
Brazil 11
Italy 8
Argentina 5
France 5
Uruguay 5
Netherlands 5
Sweden 4
England 3
Points based on 1-4 places (I gave 5 points to 1st place and 3-2-1 points to 2nd-3rd-4th place)
Germany 41
Brazil 37
Italy 29
Argentina 19
France 17
Uruguay 13
Netherlands 12
Sweden 8
England 7
On continental level, Germany are the rulers of Europe as well with 3 wins and 3 silver medals (Spain has 3 wins and 1 silver), while Argentina, Uruguay and Brazil rule the Copa America, which is played 3 times as often as EC. In conclusion, I'd say Germany, Brazil, Italy are the historical big teams with closest followers being Argentina.
