"Politics are very much like war. We may even have to use poison gas at times"

This quote by Winston Churchill is a metaphor for the severe truths of politics. He is suggesting that politics can be a ruthless and unforgiving arena, where one should want to do whatever it takes to win. He implies that often, the only way to prosper is to utilize methods that are thought about unethical or dishonest. This could be translated as a warning to those who go into the political arena, that they should be prepared to do whatever it requires to win, even if it implies using techniques that are considered to be ethically incorrect. Churchill's quote is a reminder that politics can be a dangerous and unpredictable game, and that one need to be prepared to utilize any methods required to accomplish their objectives.
