The given quotation from Churchill means that no matter how strong the tyranny is, it can never overcome human crime.
Explanation:
The British political, military and writer, Sir Winston Leonard Spencer-Churchill was UK Prime Minister from 1940-145 when, during World War II, he led the Uk to victory.
This quote from Churchill implies no matter how strong a dictatorship is that human evil cannot be defeated and that will ultimately be undermined when the tyranny is triggered by people who want to destroy it. Â
The war of any of our strength and endurance which God has given to us has never been exceeded in the dark, deplorable catalog of a human criminal act to make war towards such a monstrous tyranny.
