“I am profoundly convinced that every nationalism offers humanity only the greatest unhappiness …. It is true that the nationalism of oppressed peoples – as a natural self-defensive reaction – is much more excusable than the nationalism of peoples who oppress; but, if the nationalism of the strong is ignoble, the nationalism of the weak is imprudent; both give birth to and support each other…”
Ludwik Lejzer Zamenhof, 1914
