Answer: d. Roosevelt and Churchill decided to focus on the greater threat first.
The strategy of the Allied forces was to focus on Europe first, and deal with the threat in the Pacific afterwards. The main reason was that two allied capitals (London and Moscow) could be directly treatened by Germany, while Japan could not directly threaten any capitals. The United Kingdom was particularly vulnerable to attacks from Germany, as Germany had alreday overrun most countries in Western Europe. It was also believed that if Germany was defeated, Italy and Japan would be severely weakened. Despite the attack on Pearl Harbour, the United States maintained this "Europe First" policy.
