Who are the toughest and stronger boxers, Irish (Irish American included) or Eastern Europeans?

There is no such thing, It don't mattter if the fighter is from North America, Central America, South America, West Indies, Africa, Europe, Middle East, or Asia, History has shown us that many great fighters and fighting systems prevail from the 4 corners of the earth.
