“The victory or defeat of the revolution can be determined only over a long period of time. If it is badly handled, there is always the danger of a capitalist restoration. All members of the party and all the people of our country must not think that after one, two, three, or four great cultural revolutions there will be peace and quiet. They must always be on the alert and must never relax their vigilance.”

— Mao Zedong

“What is Juche [the subject] in our Party's ideological work? What are we doing? We are not engaged in any other country's revolution, but precisely in the Korean revolution. This, the Korean revolution, constitutes Juche in the ideological work of our Party. Therefore, all ideological work must be subordinated to the interests of the Korean revolution.”

Kim Il-sung (1912–1994) President of the Democratic People's Republic of Korea

“Our adversaries have not abandoned their ambitions, our dangers have not diminished, our vigilance cannot be relaxed. But now we have the military, the scientific, and the economic strength to do whatever must be done for the preservation and promotion of freedom. That strength will never be used in pursuit of aggressive ambitions — it will always be used in pursuit of peace. It will never be used to promote provocations — it will always be used to promote the peaceful settlement of disputes.”

John F. Kennedy (1917–1963) 35th president of the United States of America

“It is wrong to think that belief in freedom always leads to victory; we must always be prepared for it to lead to defeat. If we choose freedom, then we must be prepared to perish along with it.”

Karl Popper (1902–1994) Austrian-British philosopher of science

Source: On Freedom (1958)
Context: It is wrong to think that belief in freedom always leads to victory; we must always be prepared for it to lead to defeat. If we choose freedom, then we must be prepared to perish along with it. Poland fought for freedom as no other country did. The Czech nation was prepared to fight for its freedom in 1938; it was not lack of courage that sealed its fate. The Hungarian Revolution of 1956 — the work of young people with nothing to lose but their chains — triumphed and then ended in failure. … Democracy and freedom do not guarantee the millennium. No, we do not choose political freedom because it promises us this or that. We choose it because it makes possible the only dignified form of human coexistence, the only form in which we can be fully responsible for ourselves. Whether we realize its possibilities depends on all kinds of things — and above all on ourselves.
