The Churchillian requirement
"It is necessary that constancy of mind, persistency of purpose, and the grand simplicity of decision shall guide and rule the conduct of the English-speaking peoples in peace as they did in war. We must, and I believe we shall, prove ourselves equal to this severe requirement." Winston Churchill, during the 1946 speech in Fulton, Missouri.
Currently the leaders of the US and UK seem to be failing the requirements of Churchill.
