Justice!

Great quote attributed to but that Winston Churchill did NOT say:

"You can always count on Americans to do the right thing - 

after they've tried everything else."

Quote Investigator says the following about the idea behind the original quote: [A] variant of this saying was employed by Abba Eban who was an Israeli politician and diplomat. In March 1967 Eban visited Japan, the New York Times reported on a remark that he made[.] Commenting that the passage of time offered the best hope of an end to the problems of Israel and her neighbors, he said: 

"Men and nations behave wisely when they have exhausted all other resources."

Winston Churchill said many witty things. This was probably not among them.
