Greatest Leaders from the past 100 years

Ran across an interesting list from Time (from 8 years ago) on who they ranked as the greatest 100 leaders of the last century (the list came out in 2000). So thought I would attempt to put together my own top ten greatest leaders list from the last 100 years. Here you go:

1. Martin Luther King

2. Ronald Reagan

3. Winston Churchill

4. Mother Teresa 

5. Billy Graham 

6. Franklin Roosevelt

7. Nelson Mandela 

8. Walt Disney 

9. Gandhi 

10. Oprah Winfrey 

Do you agree? Who would you add or take off?
