I greatly admire the speech given by King George VI just prior to entering WW2:

"...For we are called, with our allies, to meet the challenge of a principle which, if it were to prevail, would be fatal to any civilized order in the world. It is the principle which permits a state, in the selfish pursuit of power, to disregard its treaties and its solemn pledges; which sanctions the use of force, or threat of force, against the sovereignty and independence of other states. Such a principle, stripped of all disguise, is surely the mere primitive doctrine that 'might is right'."

This is not vitriol, this is not heated invective. This speech places its doctorly fingers on the pulse of an ill beast, announces the disease, and determines that it must be put down.

This is political speech, but speech that is both truthful and powerful because it is not overblown.

Can we also refine our speech - like the speech of this king - to articulate what future humanity deserves? Without vitriol, without invective, without soundbites, but with moral clarity.
