In a private letter recently revealed to the public, renowned physicist Albert Einstein berated the United States for not doing enough to defeat Nazi Germany.

“If Hitler were not a lunatic he could easily have avoided the hostility of the Western powers. That he is a lunatic is the sole advantage in the present sinister picture of the world,” the Jewish scientist wrote in 1942, the Daily Mail reported on Thursday.

He concluded that the White House was “controlled to a large degree by financiers, the mentality of whom is near to the fascist frame of mind,” and expressed dismay over America’s relations with other countries.

“Why did Washington help to strangulate Loyalist Spain?” Einstein asked. “Why has it an official representative in fascist France? Why does it not recognize a French Government in Exile? Why does it flirt with Franco-Spain? Why is there no really serious effort to assist Russia in her dire need?”

Einstein voiced these concerns in a letter he sent to Dr. Frank Kingdon, president of Princeton University, where Einstein was teaching at the time. Its contents were released to the public after it was auctioned off for 30,000 euros, which comes out to a little over $34,000.

Einstein ended his letter saying that he found “refuge and protection” in America after fleeing fascist persecution in Nazi Germany, and thanking Kingdon for his “indefatigable efforts in the service of humanity and justice.”
