By the spring of 1941, there was no longer any doubt that America was gearing up for war. In March, Roosevelt announced Lend-Lease aid to Great Britain, and in May, he declared a state of “unlimited national emergency.” Such support for Great Britain did nothing to ease American relations with Japan. In July, determined to stop further Japanese expansion beyond Indochina, the United States, Great Britain, and the Netherlands acted in concert to shut off the flow of raw materials upon which the Japanese war machine relied. The three countries instituted an embargo against Japan of oil, steel, and other strategic imports. Roosevelt froze Japanese assets in the United States, closed the Panama Canal to Japanese shipping, and recalled Major General Douglas MacArthur to active duty to defend the Philippines. Far from slowing Japan’s war-making capabilities, these actions, particularly the oil embargo, served only to increase the urgency Japan felt to subjugate China and gobble up oil and rubber from the East Indies. By September, after a German U-boat fired a torpedo at the American destroyer Greer (DD-145) while it was on convoy duty in the North Atlantic, Roosevelt authorized a shoot-on-sight policy against U-boats. A month later, the destroyer Reuben James (DD-245) spotted a periscope too late and caught a torpedo that blew off its bow. The ship sank in five minutes. Out of a complement of 143 officers and men, only 44 enlisted men survived.
