At the Arcadia Conference in January, 1942, what argument persuaded President Roosevelt and Prime Minister Churchill to pursue a “Europe-first” strategy?

Germany posed the most immediate danger to the Allied war effort: it was threatening Great Britain and the Soviet Union, both of which were fighting Germany. Roosevelt and Churchill therefore agreed to concentrate first on defeating Germany while containing Japan in the Pacific. The argument was not that Japan was the strongest Axis power or that Germany was sending reinforcements to Japan.
