In 1966,
Lee Kuan Yew gave a speech at the University of Singapore speaking about Singapore's place in the world.
In his speech, he quoted a Chinese proverb: "Big fish eat small fish; small fish eat shrimps".
There are different types of shrimps, he said. Some develop defence mechanisms while others are poisonous: "If you eat them, you will get digestive upsets."
Given the size of other countries and their military capabilities, Singapore was merely a shrimp in the global sea.
According to him,
we had to at least become a poisonous shrimp. If not, we may very well be absorbed by the "bigger fish".
