In a free country, the man who reaches the position of leader is usually one of outstanding, character and ability. Moreover, it is usually possible to foresee that he will reach such a position, since early in life one can see his qualities of character. But this is not always true in the case of a dictator; often he reaches his position of power through chance, very often through the unhappy state of his country.
The passage seems to suggest that
(a) a leader foresees his future position
(b) a leader is chosen only by a free country
(c) a leader must see that his country is free from despair
(d) despair in a country sometimes leads to dictatorship
