Creating a world war requires enormous preplanning, all belligerents must be well armed and aggrieved enough to potential for victory and moral justification. FDR staged provocations in the Atlantic and on Sept 4, 1941 the USS Greer dropped 19 depth charges on German U-652, followed by USS Kearny and USS Reuben James. When German declared war on the US, Dec 8, 1941 it was not over Pearl Harbor, but over gross violations of Neutrality Laws, as described by the History Guy >
“The Undeclared War, USS Greer, USS Kearny, USS Reuben James” > it is history that deserves to be remembered
