NEW YORK POST, Nov. 10, 1941 

* Winston Churchill's Mansion House speech 
* Declares England with fight against Japan 
* If they attack U.S. - World War II - WWII

The front page has a nice banner headline: "'WE'LL JOIN U. S. IN HOUR IF JAPS FIGHT'--CHURCHILL" (see images)
Complete with all 26 pages, light toning and minor wear at the margins, some small binding holes along the spine, generally nice.

Background: The historical significance of Churchill’s November 10, 1941 speech lies in its role as the definitive geopolitical bridge between a predominantly European conflict and a truly global war. By explicitly binding the destiny of the British Empire to the United States in the Pacific, Churchill effectively erased any remaining diplomatic ambiguity, signaling to Tokyo that an attack on American soil would instantly trigger a two-front war against the world's most powerful democratic alliance. His public gamble—underlined by the immediate dispatch of capital ships like the HMS Prince of Wales to Singapore—was designed to exploit Japan's acute industrial vulnerabilities, particularly its reliance on imported resources compared to America's staggering steel production. Although this final deterrent ultimately failed to prevent the attack on Pearl Harbor just 27 days later, the address successfully primed the British public for an imminent, massive expansion of the war, solidified the foundational architecture of the Grand Alliance, and ensured that when the global flashpoint arrived, the Western Allies stood in absolute, instantaneous alignment.
