Why did Roosevelt support 'Europe First' strategy?

Roosevelt supported the 'Europe First' strategy because he viewed Nazi Germany as the most immediate and significant threat to global security and democracy. By focusing efforts on defeating Germany before fully engaging in the Pacific theater against Japan, he aimed to prevent the Axis powers from gaining further strength. This approach also allowed for the pooling of resources and coordination among Allied nations, maximizing the effectiveness of military operations against a common enemy. Ultimately, Roosevelt believed that securing victory in Europe was crucial for ensuring long-term peace and stability.
